What is the role of a substrate in an enzymatic reaction?

Back

The substrate is the reactant that an enzyme acts upon.

Front

What is a product in the context of enzyme reactions?

Back

The product is the substance formed as a result of an enzymatic reaction.

What is a catalyst?

Back

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

Front

What are biological catalysts?

Back

Enzymes that facilitate biochemical reactions in living organisms.

Front

What happens to an enzyme after a reaction?

Back

The enzyme is not consumed and can be reused for subsequent reactions.

Front

What factors affect enzyme activity?

Back

Temperature, pH, substrate concentration, and enzyme concentration.

Front

What is the active site of an enzyme?

Back

The specific region on the enzyme where the substrate binds.

Front

How do temperature changes affect enzyme activity?

Back

Increased temperature generally increases enzyme activity up to a certain point, after which the enzyme may denature.
