Enzymes

Enzymes are biological catalysts that speed up the rate of chemical reactions without being changed or

used up in the reaction. They're also proteins

Enzymes are specific to

are specific to one particular substrate(s) as the active site of the enzyme, where the substrate attaches, is a complementary shape to the substrate

increasing temperature

increases collisions

low temperatures

do not denature enzymes, they just slow down

If temperature goes past optimum

enzymes denature and change shape, so they're not complimentary to the subtrate
