Explanation / Answer

13 - True.

Change in energy depend upon whether heat is absorbed or released.

14 - Option A, ATP is the correct answer. It contains high energy bonds.

15 - Option C is the correct answer that is active site.

Active site has key amino acids that makes critical bonds with the substrate and carry out the reaction.

16 - True.

Anabolic reactions are synthesis reactions and catabolic reactions are breaking down of molecules
