How is energy stored when ADP is converted to ATP?

Answers

Answer:

Energy is stored in the bonds between the phosphate groups (PO4-) of the ATP molecule. When ATP is broken down into ADP (adenosine diphosphate) and inorganic phosphate, energy is released. When ADP and inorganic phosphate are joined to form ATP, energy is stored.

which of the following is not a condition that must be made for hardy-weinberg equilibrium 1.no mutation 2.no migration 3.domunant alleles nore frequent than recessive allels 4.large population 5. no natural selection guy please answer this one​

Answers

Answer:

3.dominant alleles more frequent than recessive alleles

Explanation:

To achieve hard-Weinberg equilibrium, certain conditions must be made.

These conditions are:

1. There is noo mutation,

2. Existence of random mating,

3. There should be no natural selection

4. There is the infinite population size

5. No migration

Hence, in this case, the correct answer is option 3, which is not a condition to be made for Hard-Weinberg equilibrium

Low-carbohydrate diets became popular in the late 1990s and were quickly proclaimed to be a fast and easy method of weight loss. The effectiveness and safety of these diets are dependent on the activity and overall health of the individual as well as the total nutritional content of the diet. However, it is true that in some cases, these diets have been effective. What metabolic effects caused by eating a low-carbohydrate diet can be linked directly to a decrease in fatty acid synthesis and an increase in fatty acid oxidation?

a. release of insulin from pancreatic's cells
b. dephosphorylation of AMPK
c. release of glucagon from pancreatic's cells
d. phosphorylation of AMPK

Answers

Answer:

c. release of glucagon from pancreatic's cells

d. phosphorylation of AMPK

Explanation:

Low-carbohydrate diets (LCDs) stimulate the secretion of glucagon by a decrease in the blood glucose concentration. Glucagon is a key hormone secreted by pancreatic cells in the same way as insulin but in an opposite way. This hormone (glucagon) prevents glucose accumulation as hepatic glycogen, while insulin helps to the accumulation of glucose in the liver as glycogen, thereby acting to reduce hepatic glucose output. Moreover, the AMP-activated protein kinase (AMPK) is a kinase protein that mediates the phosphorylation and inhibition of acetyl-CoA carboxylase (ACC) in order to reduce the synthesis of malonyl-CoA, a key molecule that regulates myocardial fatty acid oxidation.

The structure labelled A in the figure is a centromere.

What is a centromere?

The centromere is a region of the chromosome that is constricted. The centromere plays an important role in the division of cells during both the processes of mitosis and meiosis.

The centromere is simply the region of the chromosome where the spindle fibres attach. Therefore, when the spindle fibres attach to the centromere, they pull the sister chromatics in the opposite directions of the cell during cell division.

Thus, at the end of the cell division, each of the daughter cells gets one-half of the chromosome containing identical DNA. The centromere is thought to be the middle region of the chromosome, even though it is often not in the middle. It is simply the region where the chromosomes are most constricted

The centromere separates the chromosome into the P arm and the Q arm. These are simply the names given to the short arm and the long arm of the human chromosome respectively.

What kind of mutation would occur if a sequence of DNA is changed from ATCGGCTTAACG to ATCGGCTAAACG?

Answers

Answer:

Base substitution mutation

Explanation:

Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:

ATCGGCTTAACG to ATCGGCTAAACG

This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.
