AP Unit 3 Review (Energy & Enzymes)

Front

What effect does temperature have on enzyme activity?

Back

As temperature increases, there are more collisions between enzyme and substrate, which can enhance enzyme activity.

Front

What indicates that a reaction is exergonic based on energy levels?

Back

The products have less available energy than the reactants.

Front

To which category of organic molecules do most enzymes belong?

Back

Proteins.

Front

How does a competitive inhibitor interact with a substrate?

Back

A competitive inhibitor competes with the substrate by binding to the same enzyme.

Front

What is the benefit of allosteric regulation in organisms?

Back

It prevents resources from being wasted.

Front

Define enzyme activity.

Back

Enzyme activity refers to the rate at which an enzyme catalyzes a reaction.

Front

What is the role of substrates in enzyme reactions?

Back

Substrates are the reactants that enzymes act upon to facilitate a chemical reaction.

Front

Explain the concept of activation energy.

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

What is the significance of enzyme specificity?

Back

Enzyme specificity ensures that enzymes only catalyze specific reactions, which is crucial for metabolic regulation.

Front

Describe the effect of pH on enzyme activity.

Back

Each enzyme has an optimal pH range; deviations can lead to decreased activity or denaturation.
