1

What happens to an enzyme after it catalyzes a reaction?

It can be reused

It is transformed into a coenzyme

It is used up

It becomes a part of the product

Nødvendig

1

What happens when an enzyme gets denatured?

It divides into two smaller enzymes that loses function

Its size increases to bind to multiple substrates

It forms another enzyme to bind to new substrates

Its active site changes shape so it can no longer bind to the substrate

1

Which condition(s) can denature an enzyme?

Drastic change in pH levels

Lack of oxygen

Extreme heat or cold

Presence of water
