Aside from maintaining the integrity of its hereditary material, the MOST important general metabolic concern of a cell is:
A) keeping its glucose levels high.
B) maintaining a constant supply and concentration of ATP.
C) preserving its ability to carry out oxidative phosphorylation.
D) protecting its enzymes from rapid degradation.
E) running all its major metabolic pathways at maximum efficiency.

Question

Quizplus · Accepted Answer

ATP is the main source of energy for cellular processes, and the maintenance of a constant supply and concentration of ATP is essential for the metabolic needs of the cell. Failure to maintain ATP levels can lead to cell death or dysfunction. While glucose levels are important, they are not the MOST important general metabolic concern. The preservation of oxidative phosphorylation and the protection of enzymes from degradation are important, but not as critical as the constant supply and concentration of ATP. Running all metabolic pathways at maximum efficiency is not always the most important considering the need for regulation and response to changing environmental conditions.
