In another experiment, the embryologist measured the rate of synthesis of a single protein and found that the synthesis rate varied with the amount of oxygen provided to the embryos. which of the following enzymes is least likely to affect the synthesis of the protein in question?

The correct answer is option A) "Triose Phosphate Isomerase".

Explanation:

The missing options of this question are:

A) Triose Phosphate Isomerase

B) Cytochrome C oxidase

C) ATP synthase

D) Pyruvate Dehydrogenase

And the correct answer is option A) "Triose Phosphate Isomerase".

Triose Phosphate Isomerase (TPI) is a enzyme that catalyzes the conversion of dihydroxyacetone phosphate to D-glyceraldehyde 3-phosphate. This reaction is part of the glycolytic pathway, an important process of most cells to metabolize glucose. The glycolytic pathway is performed under aerobic and anaerobic conditions, therefore it is least likely that the TPI enzyme affects the synthesis of the protein according to the amount of oxygen provided to the embryos.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
