Front

How do enzymes affect activation energy?

Back

Enzymes decrease the activation energy required for a reaction.

Front

What is denaturation in enzymes?

Back

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

Front

What factors can affect enzyme activity?

Back

Temperature, pH, substrate concentration, and the presence of inhibitors.

Front

What is the optimum pH for an enzyme?

Back

The pH at which an enzyme is most active.

Front

What is an inhibitor?

Back

A substance that binds to an enzyme and prevents the substrate from binding.

Front

What happens to enzyme activity at high temperatures?

Back

Enzyme activity may increase up to a certain point, but excessive heat can lead to denaturation.

Front

What is a substrate?

Back

The reactant molecule that an enzyme acts upon.

Front

What is the active site of an enzyme?

Back

The specific region of an enzyme where the substrate binds.
