you are studying the movement of a positively charged substance into epithelial cells grown in culture. you determined that you can only find the substance inside the cell when atp is present. how is this particular substance getting through the membrane?

Answers

Answer 1

The positively charged substance is moving through the membrane through active transport when ATP is present.

Active transport refers to the movement of molecules or ions through the cell membrane against their concentration gradient, which is from an area of lower concentration to an area of higher concentration.

Active transport necessitates the use of cellular energy (ATP) to transport molecules across the cell membrane. Active transporters are a type of integral membrane protein that is often responsible for this task. The positively charged substance, in this case, is likely being transported by a type of active transport known as primary active transport.

Primary active transport uses ATP to move molecules against their concentration gradient. To achieve this, transporters must directly utilize ATP as an energy source, such as through the hydrolysis of ATP. The positively charged substance is transported against the concentration gradient in this way.

6 of 396 of 39 items question humans, like all other animals, are consumers, meaning they need to eat food for energy because they cannot make their own. which energy transformation is taking place when an animal eats food so it can keep warm? responses mechanical to thermal mechanical to thermal

Answers

The energy transformation that occurs when an animal eats food to keep warm is mechanical to thermal energy.

What is Energy transformation?

Energy transformation is the process of changing one form of energy into another form of energy. The law of conservation of energy states that the energy cannot be produced or destroyed. It can only be transformed from one form to another. There are many examples of energy transformations that take place in our daily lives. When we light a matchstick, for example, chemical energy is converted to heat energy. When a ball is thrown upwards, kinetic energy is converted to potential energy.

When a car is moving, chemical energy in fuel is converted to kinetic energy of the car's movement. And so on. Animals require energy to live, grow, and move. This energy comes from the food they eat. When animals eat food, the food is broken down into its constituent molecules and converted into usable energy through a process called cellular respiration. During this process, the energy stored in the food is transformed from chemical energy to mechanical energy, which is used by the animal to move its muscles and perform physical work. Some of this mechanical energy is lost as heat, which is thermal energy. This thermal energy helps the animal maintain its body temperature and keep warm.

Therefore, mechanical to thermal energy transformation takes place when an animal eats food so it can keep warm.

if i'm walking down the riverbank, and a man is drowning, even if i don't know how to swim very well, i feel this urge that the right thing to do is to try to save that person. evolution would tell me exactly the oppo preserve your dna. who cares about the guy who's drowning?

Answers

The evolution theory posits that living organisms have evolved over time from earlier and different forms. The theory of evolution through natural selection was first introduced by Charles Darwin.

He suggested that species that are more suited to their environment would survive and reproduce more effectively compared to other species that are less suited to their environment.

What is the urge to save people drowning?

If you are walking down the riverbank, and a man is drowning, even if you don't know how to swim very well, you feel this urge that the right thing to do is to try to save that person. This is because humans are empathic beings, which means that we can feel the emotions of others. When we see someone in distress, we feel their pain and want to help in any way that we can.

The urge to save someone who is drowning is not necessarily driven by the theory of evolution. Instead, it is a result of our innate empathy, compassion, and the desire to help others. Helping others is an essential part of being human, and it is something that we do instinctively because we care about the well-being of others. Therefore, the idea that evolution would tell us to preserve our DNA by ignoring someone who is drowning is not accurate.

The antibiotic also killed the symbiotic bacteria that fix nitrogen for the plants. Without a source of nitrogen, the plants did not grow

Answers

The most likely reason the crop did not grow well after the farmer treated the soil with a fertilizer containing an antibiotic is that (D) the antibiotic also killed the symbiotic bacteria that fix nitrogen for the plants. Without a source of nitrogen, the plants did not grow well.


The farmer treated the soil with a fertilizer containing an antibiotic to kill a bacterial plant pathogen. The antibiotic in the fertilizer not only targeted the harmful bacteria but also affected the beneficial bacteria in the soil. The beneficial bacteria, known as symbiotic bacteria, play a crucial role in fixing nitrogen for plants.


Nitrogen fixation is a process in which atmospheric nitrogen is converted into a form that plants can use as a nutrient to support their growth. When the antibiotic killed the symbiotic bacteria, the plants lost their primary source of nitrogen, which is an essential nutrient for their growth and development.

As a result, without the necessary nitrogen, the plants could not grow well, leading to poor crop yield.

In conclusion, option D is the most likely scenario for the crop not growing well after the soil was treated with a fertilizer containing an antibiotic. The antibiotic inadvertently killed the symbiotic nitrogen-fixing bacteria, causing the plants to lack the necessary nitrogen to grow and thrive.

Answers

The following steps amplify the epinephrine signal response in cells: receptor activation of G protein, G protein activation of adenylyl cyclase, and cAMP activation of PKA. Therefore, the correct option is 2, 3, and 4.

How does the epinephrine signal response amplify in cells?

Epinephrine (also known as adrenaline) is a hormone that activates a cascade of signaling pathways in the body. When epinephrine binds to its receptor on the surface of a cell, it triggers a series of events that culminate in the cell's response. The epinephrine signal response amplifies through a series of steps that are described below:

Receptor activation of G protein: The epinephrine receptor is coupled to a G protein, which is a molecular switch. When the receptor is activated by epinephrine, the G protein is activated as well.

G protein activation of adenylyl cyclase: The activated G protein, in turn, activates an enzyme called adenylyl cyclase. Adenylyl cyclase converts ATP into cyclic AMP (cAMP), which is a second messenger.

cAMP activation of PKA: cAMP activates a protein kinase called protein kinase A (PKA). PKA is a kinase that phosphorylates (adds a phosphate group to) target proteins.

PKA phosphorylation of glycogen phosphorylase kinase (GPK): One of the targets of PKA is glycogen phosphorylase kinase (GPK). PKA phosphorylates GPK, which then phosphorylates glycogen phosphorylase. This, in turn, activates glycogenolysis, the breakdown of glycogen into glucose-6-phosphate.

Answers

Extrachromosomal DNA is critical to the antibiotic resistance found in microorganisms. These DNA elements account for the phenomena by providing resistance genes that can be shared among bacteria, allowing them to survive exposure to antibiotics.

What are Extrachromosomal DNA?

Extrachromosomal DNA are also known as plasmids, and these can be passed between bacteria through a process called conjugation. This allows resistance genes to be shared between bacteria, increasing the prevalence of antibiotic-resistant strains. In addition, some extrachromosomal DNA contains genes that produce enzymes that can break down antibiotics, rendering them ineffective against the bacteria carrying these genes. This is known as enzymatic resistance.

Extrachromosomal DNA can also provide bacteria with the ability to pump antibiotics out of their cells more effectively, preventing the antibiotics from reaching their intended targets within the bacteria. This is known as efflux-mediated resistance. In summary, extrachromosomal DNA plays a critical role in the development of antibiotic resistance in microorganisms.

Once it enters the cytoplasm of a host cell and sheds its capsid, replication of HIV begins when _____ _____ is used to synthesize a double strand of DNA from the viral RNA.

Answers

Once it enters the cytoplasm of a host cell and sheds its capsid, replication of HIV begins when reverse transcriptase is used to synthesize a double strand of DNA from the viral RNA.


Once it enters the cytoplasm of a host cell and sheds its capsid, replication of HIV begins when reverse transcriptase is used to synthesize a double strand of DNA from the viral RNA.

What is HIV?HIV stands for Human Immunodeficiency Virus, a virus that attacks and weakens the immune system of humans. HIV replicates in the host cell cytoplasm after shedding its capsid, and it is called replication. When the reverse transcriptase enzyme is used to create a double-stranded DNA from the viral RNA, replication begins. HIV attacks the T-helper cells in the immune system, which are in charge of defending the body against foreign invaders. HIV gets into the bloodstream and travels to the CD4 T-helper cells after being contracted. The virus begins to reproduce after it has entered the host cell's cytoplasm. The viral RNA then acts as a template for reverse transcriptase, an enzyme that catalyzes the creation of a DNA copy of the RNA. The RNA template is destroyed and a second DNA strand is created by the same enzyme, reverse transcriptase. This second DNA strand is complementary to the first and forms a double-stranded DNA molecule.

Which of the following is/are required in order for an endosome to be transported from the plasma membrane to the Golgi complex? (Select all that apply!) GTP Kinesin Myosin Microtubules Dynein Actin ATP

Answers

The following are required in order for an endosome to be transported from the plasma membrane to the Golgi complex: GTP, Kinesin, Dynein, and Microtubules. The correct options are A, B, D and E.

An endosome is a membrane-bound compartment that is formed through the internalization of material from the plasma membrane through the process of endocytosis. Endosomes are known to sort their cargo and then subsequently recycle it back to the plasma membrane or traffic it to lysosomes for degradation. Endosomes are transported from the plasma membrane to the Golgi complex by a motor protein called kinesin. Kinesin is a plus-end-directed motor protein that is responsible for transporting cargo towards the plus end of microtubules. Dynein is another motor protein that transports cargo towards the minus end of microtubules. GTP is an energy-rich molecule that is required for the movement of the motor proteins, kinesin and dynein. This energy is used to power the movement of the motor proteins along microtubules.

Actin and Myosin are motor proteins that are responsible for transporting cargo along actin filaments. They are not involved in the transport of endosomes from the plasma membrane to the Golgi complex. ATP is the energy currency of the cell, and it is required for the movement of motor proteins. Therefore, the correct options are A, B, D, and E.
