Front

What is the molecule that binds to the enzyme called?

Back

Substrate

Front

Which of the following is NOT a job of proteins in the body: storing genetic information, providing structure, speeding up chemical reactions, or transporting substances through cell membranes?

Back

Storing genetic information

Front

What is a catalyst?

Back

A chemical that speeds up the rate of a chemical reaction.

Front

How do enzymes affect the speed of a reaction and the energy required?

Back

Enzymes make a reaction go faster and use less energy.

Front

What are proteins made of?

Back

Amino acids.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up reactions without being consumed.

Front

What is the difference between a substrate and a product in enzyme reactions?

Back

A substrate is the reactant that binds to the enzyme, while a product is the result of the reaction.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, and substrate concentration.

Front

What happens to an enzyme when it is denatured?

Back

It loses its functional shape and can no longer catalyze reactions.
