What is a catalyst?

Back

A substance that increases the rate of a chemical reaction without being consumed.

Front

What is the optimum pH for an enzyme?

Back

The pH at which an enzyme is most active.

Front

What happens to enzyme activity at extreme pH levels?

Back

Enzyme activity typically decreases and can lead to denaturation.

Front

What is denaturation in enzymes?

Back

The process where an enzyme loses its functional shape and activity due to external factors like temperature or pH.

Front

What role do enzymes play in metabolism?

Back

They facilitate biochemical reactions necessary for metabolism.
