a

Energy is released from bonds.

When ATP (adenosine triphosphate) is converted to ADP (adenosine diphosphate), energy is released from bonds. So, the correct answer is A: Energy is released from bonds.

The correct answer is (a) Energy is released from bonds when ATP (adenosine triphosphate) is converted to ADP (adenosine diphosphate).

ATP is a molecule that stores and provides energy for cellular processes. It consists of three phosphate groups attached to the adenosine molecule. When ATP is used as an energy source, it undergoes hydrolysis, where one of the phosphate groups is removed, resulting in the formation of ADP and inorganic phosphate (Pi). This hydrolysis reaction is catalyzed by an enzyme called ATPase.

During this conversion from ATP to ADP, a high-energy phosphate bond is broken, releasing energy. This energy can be used by the cell to drive various metabolic reactions, muscle contractions, active transport across cell membranes, and other essential cellular processes. ADP can be further converted back into ATP through cellular respiration, where energy from nutrients is used to regenerate ATP.

So, when ATP is converted to ADP, energy is released from the phosphate bond, which is then harnessed to carry out cellular functions. Therefore, option (a) "Energy is released from bonds" is the correct answer.
