Answer and Explanation:

Protein is one of the most important molecules in our organism, being present in the composition of all elements, in addition to participating in several metabolic processes. This importance creates the need to study this molecule, however, to study it it is necessary to know the composition chemistry and the levels of structure it presents.

The chemical composition of proteins is related to amino acids, since protein is formed by them. In this case, we can say that the proteins have the same composition as the amino acids containing carboxylic acid and different amino groups, which is what determines the name and function of the amino acid.

In addition to chemical composition, the structure levels of proteins are extremely important, as they only function at a specific structural level. As for these levels, proteins can have a primary structure (there are more than two amino acids organized in a linear row), a secondary structure (when the primary structure turns into a helix species), a tertiary structure (formed by a more intense folding of the secondary structure providing the appearance of helices and leaves) and quarternary structure (when several tertiary structures are joined, allowing folding at the three-dimensional level. This is the functional structure of the protein).

I have mutant cells that make no pfk2enzyme. i measure rates of oxygen consumption in these mutant cells and compare them to wil
Kazeer [188]

The correct answer is that mutant cells will exhibit diminished oxygen consumption; decreased glycolysis results in decreased Kreb's cycle and electron transport chain.

The PFK2 enzyme catalyzes the generation of F26BP, this binds with the allosteric site of PFK-1 and increases the affinity of PFK-1 with F6P and also decreases the affinity of allosteric inhibitors citrate and ATP to PFK-1. Thus, PFK-1 will combine with F6P at a greater rate.

This ultimately results in more glycolysis, thus, more ETC and more consumption of O2. If there is no PFK2, then there will be a reduction in glycolysis, TCA, ETC, and consumption of oxygen.

The PFK2 is an enzyme accountable for monitoring the rates of gluconeogenesis and glycolysis in the human body. In the absence of glycolysis, there will be a reduction in TCA, ETC, and consumption of O2.
