Macromolecules and Enzymes Basics Review

Front

What are macromolecules?

Back

Large, complex molecules that are essential for life, including carbohydrates, proteins, lipids, and nucleic acids.

Front

What is the primary function of carbohydrates?

Back

To provide energy and support cellular structure.

Front

What are lipids primarily used for in the body?

Back

To store energy, form cell membranes, and act as signaling molecules.

Front

What is the role of proteins in biological systems?

Back

Proteins serve as enzymes, structural components, and play roles in transport and signaling.

Front

What are nucleic acids and their function?

Back

Nucleic acids, such as DNA and RNA, store and transmit genetic information.

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 work?

Back

Enzymes lower the activation energy required for a reaction, allowing it to occur more quickly.

Front

What is a substrate in the context of enzymes?

Back

The reactant molecule that an enzyme acts upon.

Front

What is the active site of an enzyme?

Back

The specific region on an enzyme where the substrate binds.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, and substrate concentration can all influence enzyme activity.
