Question

A phosphoanhydride bond

A) is a high-energy bond.
B) has a standard free energy of hydrolysis of −7.3 kcal/mol.
C) is broken by hydrolysis.
D) links two phosphate groups.
E) All of the above are correct.

Answer 1

A phosphoanhydride bond is a high-energy bond that links two phosphate groups. It is broken by hydrolysis and releases energy.

Step-by-step explanation:

A phosphoanhydride bond, also known as a high-energy bond, links two phosphate groups. These bonds are considered high-energy because they release a significant amount of energy when they are broken by hydrolysis. The hydrolysis of ATP, for example, results in the formation of ADP and inorganic phosphate, along with the release of energy. Therefore, the correct answer to the question is E) All of the above are correct.
