Question

what happens to an enzyme when it is denatured?
a it becomes more active.
b it changes shape and loses functionality.
c it binds more easily to substrates.
d it speeds up reactions indefinitely.

Explanation:

Enzymes are proteins. Denaturation disrupts their 3 - D structure. This change in shape makes the active - site non - functional for binding substrates, thus losing catalytic activity.

Answer:

B. It changes shape and loses functionality.
