Which statement is true?
A) High concentrations of ATP inhibit the formation of more ATP.
B) The ATP concentration in cells actually decreases at first when cells need large supplies of energy.

D) Cells constantly adjust their metabolic reactions to provide energy whenever it is needed.
E) All of these are true.

Question

Quizplus · Accepted Answer

A) High concentrations of ATP do indeed inhibit the formation of more ATP through a process called feedback inhibition.
B) The ATP concentration in cells may decrease at first when cells need large supplies of energy because ATP is quickly used up and needs to be replenished through cellular respiration.
C) The activity of many enzymes such as those involved in glycolysis, the Krebs cycle, and oxidative phosphorylation, all directly or indirectly affect ATP production in cells.
D) Cells constantly adjust their metabolic reactions through processes like cellular respiration and photosynthesis to provide energy whenever it is needed.
