Enzymes

Front

What is an enzyme?

Back

A protein that acts as a catalyst to speed up chemical reactions in biological processes.

Front

Where do substrates bind on an enzyme?

Back

Active site.

Front

What is a substrate?

Back

The substance that binds to an enzyme and is transformed during a chemical reaction.

Front

What happens to enzymes at high temperatures?

Back

They can become denatured, losing their functional shape and activity.

Front

What are the main types of biological macromolecules?

Back

Proteins, carbohydrates, lipids, and nucleic acids.

Front

What role do enzymes play in photosynthesis?

Back

They facilitate the chemical reactions that convert light energy into chemical energy.

Front

What is the effect of pH on enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can reduce activity or denature the enzyme.

Front

What is a coenzyme?

Back

A non-protein molecule that assists enzymes in catalyzing reactions.

Front

What is the relationship between enzymes and activation energy?

Back

Enzymes lower the activation energy required for a reaction to occur.

Front

What are products in a chemical reaction?

Back

The substances that are formed as a result of a chemical reaction.
