Question

What happens to an enzyme when it performs its function? What does this mean about enzyme molecules??

Answer 1

1. Enzyme interacts with substrate
. 2. Enzyme may undergo a conformational change to capture the substrate ("induced fit" model)
3. Enzyme-substrate complex may undergo several changes to form the product(s).
4. The product(s) are released
. 5. The enzyme returns to its original form. It is then ready to do the cycle all over again.
