For an enzyme to function it requires
A)oxygen.
B)a suitable substrate.
C)a considerable amount of activation energy.
D)ATP.
E)all of these.

Question

Quizplus · Accepted Answer

Enzymes require a suitable substrate in order to catalyze a specific chemical reaction. While some enzymes may require oxygen as a substrate or ATP as an energy source, these are not universal requirements for all enzymes to function. The activation energy required for a reaction is also lowered by the presence of an enzyme, but the enzyme itself does not require this energy to function. Therefore, B is the best choice for a universal requirement of enzyme function.
