What is the primary function of enzymes in biochemical reactions?

Back

Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur.

Front

Back

Amylase is an example of an enzyme.

Front

What is the role of carbohydrates in the body?

Back

Carbohydrates provide quick energy.

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where substrate molecules bind and undergo a chemical reaction.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, and substrate concentration can all affect enzyme activity.

Front

What is a substrate in the context of enzyme activity?

Back

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

Front

How do competitive inhibitors affect enzyme activity?

Back

Competitive inhibitors bind to the active site of an enzyme, preventing the substrate from binding and thus decreasing enzyme activity.

Front

What is the difference between an enzyme and a coenzyme?

Back

An enzyme is a protein that catalyzes biochemical reactions, while a coenzyme is a non-protein molecule that assists enzymes in their function.
