If you add enzyme to a solution containing only the products of a reaction would you expect any substrate to form?

A. It depends on the time interval and the temperature of the reaction

B. It depends on the concentration of products added

C. It depends on the energy difference between E + P and the transition state

D. All of the above may determine if product forms

E. None of the above determines if product forms

Answer #1

Enzymes comprised smaller portion called active site where an substrate can fit. During enzyme catalysis reaction ,substrate binds to the active site and an Enzyme-Substrate complex is formed (this state is transition state).

E +S E -S complex.

This E-S complex is unstable and the bond breaks and the substrate is transformed to product.

E-S complex E + P

In this case the formation of products depends on the transition state and E+P complex. If the enzyme can sufficiently lower the activation energy of the transition state the substrate will form.

So, option C is the correct answer.
