<span>Enzymes are crucial contributors to protein digestion. Protein-digesting enzymes are referred to as proteinases or proteases. Protein generally takes the form of very complex molecules arranged in chains of amino acids. So the bonds binding these complex molecules together must first be broken down

i think the answer is B, i may be wrong... because potential energy is stored energy and kinetic energy is energy due to motion so the less potential energy the more kinetic energy
and mechanical energy means the energy of motion, such as a moving vechile which is using kinetic energy.
