Build up

Catabolic enzymes

Break down

Do enzymes get used up?

No

What are enzymes made up of?

Large proteins made of amino acids folded into unique shapes

What is the name for the part with a specific shape?

Conditions for enzymes

They need the right temperature and Ph, otherwise the denatured which is when they lose their shape so the substrate no longer fits
