ATP is classified as an energy-rich compound because
A)it complexes with Mg²+.
B)it has a relatively low free energy of hydrolysis.
C)its complete oxidation to carbon dioxide releases a large amount of energy.
D)of the free energy released from cleavage of the phosphoanhydride bond.

Question

Quizplus · Accepted Answer

The free energy released from the cleavage of the phosphoanhydride bond in ATP is what makes it an energy-rich compound. This bond contains a large amount of potential energy, which can be harnessed by the cell to perform various energy-requiring processes. Mg²+ is not directly related to ATP's energy-richness, and the free energy of hydrolysis is actually relatively high. While complete oxidation of ATP does release energy, it is not the primary reason why ATP is considered energy-rich.
