An enzyme is protein and it needs to maintain its 3D structure as the enzyme work like "lock and key". A little deformation to the enzyme structure can disable its functions.
Protein is prone to denaturation. Condition like pH and temperature can affect the protein and cause an alteration to its structure. Higher temperature should speed up the reaction but too high temperature might damage the enzyme. So, the "optimal" condition would be the condition where the enzyme structure is not altered.
it is a most definately because it makes the most sense than the other answers do so if you don't agree with me it is fine but it might be b because it makes sense as well but I don't know for sure but who knows
Humans get there energy primarily from glucose I believe. We break down glucose to get ATP (Adenosine Triphosphate) which is then used to supply energy to our cells in order to function.
Without the graphic for reference, I'd say A. The shark population will decrease.
