Question

Question 5 options:

The shape of an enzyme allows it to function.

Almost all enzymes are proteins.

All enzymes have the same shape as their substrates.

Each enzyme only works with a specific substrate.

Answer 1

The statement that is NOT correct is:

"All enzymes have the same shape as their substrates."

This statement is incorrect because while enzymes and substrates have specific complementary shapes that allow them to bind together (like a key fits into a lock), they do not have to be the same shape. Rather, the enzyme's active site is specifically shaped to fit its substrate, but the overall shapes of the enzyme and the substrate are different.
