Why are enzymes really good catalysts? Correct Answer-Because enzyme active sites have evolved to catalyze reactions with maximum efficiency by using several catalytic mechanisms simultaneously Enzymes exhibit maximal activity under what kind of conditions? Correct Answer-Mild conditions, like conditions that exist in cells. Why are enzymes categorized as being extremely specific? Correct Answer-Because an enzyme usually catalyzes ONLY the reaction involving "its" substrate, even though ...
