All are true for the energy charge (EC) of a cell EXCEPT:
A) It is an index of adenylate phosphoric anhydrides.
B) EC has a range of 0 to 1.0.
C) It is a ratio of adenylate phosphoric anhydride bonds to total adenylate concentration.
D) It is 1.0 when all of the adenylate is ATP.
E) It is rapidly changed by adenylate kinase.

Question

Quizplus · Accepted Answer

The energy charge (EC) of a cell is not rapidly changed by adenylate kinase. Adenylate kinase plays a role in maintaining the energy balance within the cell by catalyzing the interconversion of adenine nucleotides (ATP, ADP, and AMP), but changes in EC reflect broader shifts in cellular energy states rather than rapid fluctuations.
