Q

What happens at the active site?

A

In the same way that a key fits into a lock, so a substrate is thought to fit into an enzymes active site. The enzyme is the lock and the reactant is the key

Q

What happens if the temperature and pH changes sufficiently beyond the enzymes optimum

A

The enzymes becomes denatured

17
Q

What happens when an enzymes denatured

A

It changes the shape of the enzymes which means the enzymes cannot fit into the substrate and the enzymes will no longer work.
