Predict what will happen to the concentration of pyruvate, NADH and H+ when the Krebs cycle is stopped by arsenic

Answers

Answer: Pyruvate would increase, NADH would decrease, and intermembrane H+ would decrease as well.

Explanation:

Glycolysis would raise pyruvate, but the Krebs Cycle would not produce NADH, decreasing it. No protons (H+) will be pushed into the intermembrane gap, lowering its H+ content and raising its pH.

What is Kreb's cycle?

The tricarboxylic acid (TCA) cycle, commonly referred to as the Krebs cycle or the citric acid cycle, is the primary route that cells use in order to acquire energy and is an essential component of aerobic respiration. The cycle transforms the oxidative potential of acetyl coenzyme A (acetyl CoA) into the reductive potential of nicotinamide adenine dinucleotide (NADH).

The synthesis of ATP via the Krebs cycle is disrupted when arsenic is present because it prevents pyruvate from being converted into acetyl coenzyme A (acetyl-CoA). In addition to the effects described above, arsenic also prevents glucose uptake at the cellular level, as well as gluconeogenesis, the oxidation of fatty acids, and additional acetyl-CoA formation.

C.They both produce sex cells.

D.They both produce new cells.

Answers

Answer:

D.They both produce new cells.

Explanation:

Meiosis and mitosis are both processes of cell division; however, they have many differences. Meiosis occurs in sex cells and produces haploids that can be fertilized. Mitosis occurs in body cells and produces diploids that replace old or damaged cells. Still, both processes result in the creation of new cells.

explain the importance of taking named precautions before blood transfussion can be done?​

Answers

Answer:

To minimize the chance of an adverse reaction during a transfusion, health care practitioners take several precautions. Before starting the transfusion, usually a few hours or even a few days beforehand, the person is cross-matched with the donor blood (not done for transfusions of plasma or platelets).

Precautions are necessary for blood transfusion because
There are chances of getting exposed to fatal diseases like hepatitis, AIDS and many other diseases.
And avoid the reactions between antigen and antibodies, which leads to rejection of transfused blood.

Why Darwin is known as father of evolution? Discuss how evidences against Darwinism led to formulation of modern evolutionary theory. Interpret its postulates in your words with relevant examples. (10 marks)

Answers

Answer:

Darwin was one of the greatest scientists who ever lived. He wrote the book 'The origin of species'. Darwin was known not only for the theory of evolution as we know it today, but also the foundation that biological sciences are based on. Darwin was very worried that people would reject his theory, so he collected a huge amount of evidence. He took evidence from the fossil record and from his own collections. He talked to animal breeders and animal collectors. He proved that the theory of evolution is based on the idea that all species are related and gradually change over time. His postulates is what gave him the title father of evolution

Postulates of evolution:-

1) Individuals within species are variable

2)Some of these variations are passed on to offspring

3)In every generation, more offspring are produced than can survive

4) The survival and reproduction of individuals are not random

The individuals who survive and go on to reproduce the most are those with the most favorable variation, and they are naturally selected.

Example:-

If an animal has to do the same task over and over again, it's body gradually changes to make the task easier. So if a deer reaches higher and higher into trees for food, day after day, it's neck will gradually stretch as it gets older.

If a deer's neck grows longer during it's lifetime, all it's babies will be born with long necks too.

Would an observational study or an experiment be more appropriate to investigate the effects on fertilizer on plant growth? Explain.

Answers

Answer:

Experiment

Explanation:

For such an investigation an Experiment would be the better option. This is because in an experiment you would have both an experimental group and a control group. This would allow you to use fertilizer on one but not the other, therefore, providing seperate results that you can use to compare with one another. This ultimately helps you determine the actual effects that fertilizer has on the growth of plants, since the fertilizer would be the only variable in the experiment. An observational study would only allow you to observe the plants in a natural scenario, without interfering and seperating the plants into different groups with different environments.

What are fibers and their types?

The body is unable to digest fiber, which is a form of carbohydrate. While fiber cannot be converted into glucose, the sugar that results from the breakdown of most carbs, fiber travels through the body undigested.

The solubility, viscosity, and fermentability of dietary fibers, which have an impact on how they are metabolized by the body, can be used to classify them in general. Dietary fibers have a wide range of chemical compositions.

Fibre comes in two varieties: soluble and insoluble. Both are crucial for good health, digestion, and illness prevention. Thus, Pinto beans are added to tacos, burritos, and soups that are high in fiber.

Complete the sentences on the control of the cell cycle with the correct terms. After S phase ____________ appear to share a common centromere.

Answers

Answer:

After S phase sister chromatids appear to share a common centromere.

Explanation:

The cells of the different organisms go through different periods during their life, each one characteristic and well differentiated. Before the mitosis process, during the S phase of the cell cycle, the chromosomes replicate, so that at the time of initiating cell division in humans, each of the 46 replicated chromosomes will have two chromatids joined by the centromere, each one of them represents a functional chromosome. Each sister chromatid of a chromosome secretes a daughter cell, as do the other 45, and together they will make up the diploid "cluster" of 46 chromosomes from the new cell. In other words, each chromosome is made up of two chromatids that come together at a point called the centromere. One chromatid contains a condensed chromatin molecule and the other has another identical chromatin molecule, the result of DNA replication, which is why we talk about a sister chromatid chromosome. Each chromatid has two arms of equal or different length.

Describe how table salt dissolves in water in 300 words.​

Answers

Answer:

salt disloves in 300 words

Answer:

Salt (sodium chloride) is made from positive sodium ions bonded to negative chloride ions. Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions.

Explanation:

When sodium chloride is dissolved in water, the polar water molecules are able to work their way in between the individual ions in the lattice. The water molecules surround the negative chloride ions and positive sodium ions and pull them away into the solution. This process is called dissociation.
