A catalyst is a substance that speeds up a chemical reaction without being consumed in the process.

Front

Can enzymes be reused?

Back

Yes, enzymes can be used again and again after catalyzing a reaction.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes lower the activation energy required for reactions, thus speeding up the rate of the reaction.

Front

What is a substrate?

Back

A substrate is the reactant molecule that an enzyme acts upon.

Front

What happens to an enzyme after it catalyzes a reaction?

Back

The enzyme remains unchanged and can catalyze another reaction.

Front

What factors can affect enzyme activity?

Back

Factors include temperature, pH, and substrate concentration.

Front

What is enzyme denaturation?

Back

Denaturation is the process where an enzyme loses its functional shape due to extreme conditions, rendering it inactive.
