Unit 1 Check 4: Enzymes & Chemical Reactions

Front

What is an enzyme?

Back

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

Front

How do enzymes affect activation energy?

Back

Enzymes decrease the activation energy required for a chemical reaction to occur.

Front

Can enzymes be reused after a reaction?

Back

Yes, enzymes can be reused multiple times after catalyzing a reaction.

Front

What is a catalyst?

Back

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

Front

What are reactants in a chemical reaction?

Back

The starting materials that undergo change during a chemical reaction.

Front

What are products in a chemical reaction?

Back

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

Front

What does the Law of Conservation of Mass state?

Back

Matter cannot be created or destroyed in a chemical reaction; it can only change forms.

Front

What is the role of enzymes in metabolism?

Back

Enzymes facilitate and regulate metabolic reactions, allowing cells to efficiently convert substrates into products.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is an active site?

Back

The specific region on an enzyme where the substrate binds and the reaction occurs.
