Question

Why is phosphorylation endergonic?

Answer 1

Phosphorylation is endergonic because it requires energy to form an additional bond with the new phosphate group.

Explanation:

Phosphorylation is the addition of a phosphate group to a molecule. This process requires energy because it results in new bonds being formed and a more complex product being created. Because the products are of a higher energy than the reactants, it is considered endergonic.
