Which of the following statements about oxidative phosphorylation by ATP synthase is FALSE? A) The electrochemical gradient across the inner mitochondrial membrane generated by electron flow is used to synthesize ATP. B) Uncouplers dissipate the electrochemical gradient but electron transport continues without ATP production. C) Inhibitors disrupt electron flow as well as ATP synthesis. D) A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP. E) ATP synthesis occurs via simultaneous conformational changes in protein subunits containing catalytic sites.

Answers

Answer 1

Answer

D)A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP

Explanation:

Oxidative phosphorylation reffers to metabolic pathway whereby enzyme is used by the cell to achieve nutrient oxidation, so that chemical energy of molecular oxygen is released as a result of this, adenosine triphosphate (ATP) is manufactured. oxidative phosphorylation is seen in all organisms that are aerobic in nature and it occur in the mitochondria of all eukaryotic organisms. There is electron transfer during oxidative phosphorylation, the electrons moves from the donor to the receptor and this is known as redox reaction, as a result of this energy is released, and this energy is used for formation of ATP.

Therefore,among all the options, A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP is the false statement.

75 POINTS!!! One reason male peacocks spread their tail feathers is to attract a mate. How does choosing a male with a bright, full tail increase a peahen’s chance of producing healthy peachicks?

Answers

Answer:

They have greater health conditions

Explanation:

if they are bright, they are healthy

Answer:

Typically, if a peacock has a bright tail with many feathers and eyespots, a female will choose him. These tail features indicate that the peacock may be healthier than other males and, therefore, produce healthier peachicks.

Within a population of butterflies, the color brown (B) is dominant over the color white (b) and 32% of all butterflies are white. Given this simple information, which is something that is very likely to be on an exam (teehee), calculate the following:
1. The percentage of butterflies in the population that are homozygous dominant
2. The number of heterozygous butterflies if the population contained 4,216 individuals

Answers

Answer:

48% Heterozygous of the population, 12% Homozygous dominant size.

Explanation:  

Given the characteristics of its population,

Brown (B) predominates over white (b) color.

Recessive phenotype frequency (Q)= 40%= 0.4

According to the Hardy-Weinberg principle, the frequency is given by P and Q for a population with the dominant and recessive trait, where P+Q=1 preserves the equilibrium of the population allele.

So then, P = 1-Q

P=1-0.4=0.6

Heterozygotic butterflies = 2PQ

So, 2PQ= 2x0.6x0.4=0.48

That is, 48 percent of people are heterozygous

Homozygous dominant individual frequency = 1-(40 + 48) = 12 i.e. 12%

Answer:

C. 0.48

explain the process (reflex action) that happens when you pull your arm away from an open flame. use steps to explain your answer. identify the receptor in the skin, the stimulus, the neurons,the effector(muscle) and the body's response to the stimulus.

Answers

Answer:

A reflex action is defined as an involuntary action of body in response to a stimulus, which protects the body from any harmful conditions including touching open flame.

A reflex action follows a sequence of action that helps in involuntary action, tha include the stimulus, receptor in the skin, the neurons (sensory, relay and motor neurons), the effector(muscle) and resposne of body to stimulus.

In the reflex action when a person pull his/her arm away from an open flame, the stimulus will be the hot flame that send a signal to the nervous system.

The sensory receptor found in the dermis or epidermis of skin called cutaneous receptors, senses the temperature change.

Then the sensory neuron comes in action which sends electrical impulses to a relay neuron (located in spinal cord) and relay neuron sends impulse to motor neuron.

Motor neuron sends that electrical impulses to a muscle which act as an effector which allows muscle to contracts to move hand away.

So, at the end the body resposnes to move hand aways from the open flame.
