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.

Norma-Jean [14]

Answer:

The rate of photosynthesis was more than the rate of respiration

Explanation:

Photosynthesis has to do with the synthesis of sugar molecules from inorganic products such as water and carbon dioxide. Respiration on the other hand has to do with breaking down of the sugar molecule from photosynthesis to release the energy locked up in the sugar for various metabolic processes in the plant's body.

<em>If both processes are balanced, there will be no net sugar production. Hence, if an excess of sugar produced fossil fuels, it thus means that there was net production of sugar in the past. The rate of photosynthesis was more than the rate of respiration in the past.</em>
