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.

pyurvate inflow

oxygen inflow

ATP Outflow

ADP Inflow

Acetyl CoA no net change

Gluceral-3-phosphate no net flow

NADF inflow

FADH2 outflow

Oxaloacetate no net flow

water outflow

proton outflow

Explanation:

Aerobic respiration is the process in which cell get oxygen from within. There is no inflow of oxygen and the movement is minimum. The membrane covering the cell releases the excess oxygen if the initial storage is more than the requirement. This is in the form of outflow in ATP.

As the cell grows, it faces some issues such as:

• Running out of the nutrients and requirement of growth factors.

• Running out of the space.

• Require appropriate gas exchange.

As compared to the smaller cells, larger cells have more issues in moving the required materials inside and excretory products outside. This is because the ratio of the surface is to volume is turning more and more unbalanced and takes much longer time for the cellular processes to take place.

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.

Answers

Centromere

Explanation:

Connects sister chromatids

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.
