Which of the Following is NOT a Characteristic of the Energy

Question

Which of the following is NOT a characteristic of the energy charge (E.C.)of a cell?
A)It is rapidly changed by adenylate kinase.
B)E.C.has a range of 0-1.0.
C)It is a ratio of adenylate phosphoric anhydride bonds to total adenylate concentration.
D)It is 1.0 when all the adenylate is ATP.

Accepted Answer

All the other options are characteristics of the energy charge (E.C.) of a cell. The E.C. has a range of 0-1.0, and it is a ratio of adenylate phosphoric anhydride bonds to total adenylate concentration. It is also 1.0 when all the adenylate is ATP. However, the E.C. is not rapidly changed by adenylate kinase but rather reflects the balance between ATP synthesis and utilization in the cell.
