Question: 1 / 400

What is the total amount of energy released if all bonds in ATP are broken?

25,000 calories

30,000 calories

31,500 calories

The total amount of energy released when all bonds in adenosine triphosphate (ATP) are broken is approximately 31,500 calories. ATP is a high-energy molecule that stores energy in its phosphate bonds, particularly in the bonds between its last two phosphate groups. When ATP is hydrolyzed (i.e., when it reacts with water) and these bonds are broken, energy is released that can be utilized by cells for various biological processes, such as muscle contraction, cellular signaling, and biosynthesis.

The specific figure of 31,500 calories reflects the energy associated with the breakdown of ATP to adenosine diphosphate (ADP) and inorganic phosphate (Pi). This amount of energy is significant and illustrates why ATP is often referred to as the "molecular currency" of energy transfer in biological systems.
