What factors can affect enzyme activity?

Back

Temperature, pH, and substrate concentration.

Front

What is a substrate in the context of enzymes?

Back

The reactant molecule that an enzyme acts upon.

Front

What is the lock and key model of enzyme action?

Back

The model that describes how a substrate fits perfectly into the active site of an enzyme.

Front

What is enzyme specificity?

Back

The concept that each enzyme only catalyzes a specific reaction or type of reaction.
