Question

hydrolysis of which covalent bonds in atp releases a considerable amount of energy?
phosphate - phosphate bonds
carbon - hydrogen bonds
nitrogen - carbon double bonds
hydrogen bonds

Explanation:

ATP (adenosine - tri - phosphate) has high - energy phosphate - phosphate bonds. When these bonds are hydrolyzed, a significant amount of energy is released. Carbon - hydrogen, nitrogen - carbon double bonds and hydrogen bonds in ATP are not the bonds that release large amounts of energy upon hydrolysis.

Answer:

phosphate - phosphate bonds
