Question

In the induced fit model, when a reactant temporarily binds to the active site of an enzyme, the enzyme __________.

A.attaches salt to the reactant
 B.cools down the reactant’s temp.
 C.slightly changes reactant's shape
 D.heats up the reactant’s temperature

​

Answer 1

Answer:

C. Slightly changes the reactant's shape.

Explanation:

In the induced fit model, when a reactant temporarily binds to the active site of an enzyme it slightly changes reactant's shape.

The binding of substrate to the enzyme induces conformation change in enzyme that results in a complementary fit once the substrate is bound.

The binding site has a different three dimensional shape before the substrate is bound.

When substrate is bound and transition state is formed, the bonds are rearranged.

Once the product is formed, it is released from the enzymes binding site.
