Question

question 31
which part of atp holds the high energy bond?
the bond between the second and third phosphates.
the bond between ribose and the first phosphate.
the bond between the first and second phosphates.
the bond between adenine and ribose.

Explanation:

ATP (adenosine triphosphate) has two high - energy phosphate bonds. These bonds are between the phosphate groups. Specifically, the bond between the second and third phosphates is a high - energy bond. When this bond is broken (hydrolyzed), energy is released. The bond between ribose and the first phosphate is not a high - energy bond. The bond between adenine and ribose is also not a high - energy bond. And while the bond between the first and second phosphates is a phosphate - phosphate bond, the more commonly referred to high - energy bond in the context of energy release for cellular work is the one between the second and third phosphates.

Answer:

The bond between the second and third phosphates.
