Question

How do enzymes change the rate of a chemical reaction?

• A. Enzymes increase the speed of reactant particles.
• B. Enzymes decrease the rate of the reverse reaction.
• C. Enzymes stabilize the rate of the product formation.
• D. Enzymes increase the rate of collisions between reactant particles.

Answer 1

The correct option is A Enzymes increase the speed of reactant particles.

To complete any reaction there is a potential barrier i.e. energy, enzyme works as catalyst and lowers the activation energy for a reactant to reach the potential barier easily and fast that's how the enzyme increases the speed of rectenct particles to change in the product.

Example :- Carbonic anhydrase enezyme increase the speed million times to changethe $C{O}_2$ into bicorbonate$\left(HC{O}_3^{-}\right)$
