Section 3 - Macromolecules and Enzymes

Front

What happens to an enzyme when its shape is changed, such as by overheating?

Back

The enzyme loses its ability to catalyze a reaction.

Front

What factors affect the efficiency of an enzyme?

Back

Temperature, pH, and the amount of enzyme all affect enzyme efficiency.

Front

What is the primary function of most enzymes?

Back

Most enzymes speed up the chemical reaction.

Front

Which macromolecules are important for insulation in animal tissues?

Back

Lipids are a prominent part of animal tissues that function in insulation.

Front

What are carbohydrates formed from?

Back

Carbohydrates are formed from monomers called monosaccharides.

Front

Define enzymes.

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms.

Front

What is the role of lipids in the body?

Back

Lipids serve as energy storage, insulation, and make up cell membranes.

Front

What are the four main types of macromolecules?

Back

The four main types of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.

Front

What are proteins made of?

Back

Proteins are made of monomers called amino acids.

Front

How do enzymes lower the activation energy of a reaction?

Back

Enzymes provide an alternative reaction pathway with a lower activation energy.
