Macromolecules and Enzymes Study Guide

Front

What makes enzymes substrate specific?

Back

The function of a protein depends upon its shape, and each protein has a different shape.

Front

Which statement about enzymes is NOT true?

Back

The active sites of enzymes will fit any type of substrate.

Front

What are the building blocks of nucleic acids?

Back

Nucleotides.

Front

What element do proteins always contain that carbohydrates and lipids do not?

Back

Nitrogen.

Front

What condition will NOT typically denature enzymes in humans?

Back

Maintaining homeostasis.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes lower the activation energy required for a chemical reaction to take place.

Front

How do enzymes and substrates interact?

Back

Enzymes and substrates fit together like a lock and key.

Front

What happens to enzymes when they become denatured?

Back

They lose their functional shape and can no longer catalyze reactions.

Front

What are macromolecules?

Back

Large molecules made up of smaller subunits, including carbohydrates, proteins, lipids, and nucleic acids.

Front

What are the four main types of macromolecules?

Back

Carbohydrates, proteins, lipids, and nucleic acids.
