Macromolecules are large, complex molecules that are essential for life. They include carbohydrates, lipids, proteins, and nucleic acids.

Front

What is the primary function of carbohydrates?

Back

Carbohydrates primarily serve as a source of energy and are also involved in structural functions in cells.

Front

What are lipids and their main functions?

Back

Lipids are macromolecules that store energy, insulate the body, and make up cell membranes.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids.

Front

What is the role of nucleic acids in cells?

Back

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

Front

What is the structure of a cell membrane?

Back

The cell membrane is primarily composed of a phospholipid bilayer with embedded proteins, which controls the movement of substances in and out of the cell.

Front

What are fatty acids?

Back

Fatty acids are the building blocks of lipids and can be saturated or unsaturated.

Front

What is the difference between saturated and unsaturated fats?

Back

Saturated fats have no double bonds between carbon atoms, while unsaturated fats have one or more double bonds.

Front

What is the function of enzymes?

Back

Enzymes are proteins that act as catalysts to speed up chemical reactions in the body.

Front

What is the significance of the cell theory?

Back

The cell theory states that all living things are made up of cells, which are the basic units of life.
