Enzyme help...question?

Question

Succinate dehydrogenase catalyzes the conversion of succinate to fumarate. The reaction is inhibited by malonic acid, which resembles succinate but cannot be acted upon by succinate dehydrogenase. Increasing the ratio of succinate to malonic acid reduces the inhibitory effect of malonic acid.

What is the purpose of using malonic acid in this experiment?

It is a noncompetitive inhibitor.

It replaces the usual enzyme.

It blocks the binding of fumarate.

It is able to bind to succinate.

It is a competitive inhibitor.

Answer 1

well not sure..this sound like its an assignment..well gudluck with tht!

Answer 2

It's competitive inhibitor - it acts like a succinate, but cannot get converted by the complex II.
