Phosphate Groups May Be Transferred from One Molecule to Another

Question

Phosphate groups may be transferred from one molecule to another during
A) hydrolysis reactions only.
B) addition reactions only.
C) dehydration reactions only.
D) exchange reactions only.
E) addition and exchange reactions.

Accepted Answer

Phosphate groups can be transferred from one molecule to another in two ways: addition reactions, where a phosphate group is added to a molecule, and exchange reactions, where a phosphate group is transferred from one molecule to another. Dehydration and hydrolysis reactions involve the removal or addition of water molecules, respectively, and do not necessarily involve phosphate group transfer. Therefore, option E is the best choice.
