What are macromolecules?

Back

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

Front

What are the four main classes of macromolecules?

Back

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

Front

What is the primary function of proteins?

Back

Proteins serve various functions including acting as enzymes, structural components, and signaling molecules.

Front

What are nucleic acids and their primary function?

Back

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

Front

What are carbohydrates and their primary function?

Back

Carbohydrates are organic compounds that serve as a primary energy source and structural components in cells.

Front

What are lipids and their primary function?

Back

Lipids are hydrophobic molecules that store energy, form cell membranes, and act as signaling molecules.

Front

What role do enzymes play in biological processes?

Back

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

Front

What is the structure of DNA?

Back

DNA is a double helix composed of nucleotides, which include a sugar, phosphate group, and nitrogenous base.

Front

How do carbohydrates differ from lipids?

Back

Carbohydrates are primarily used for energy and are soluble in water, while lipids are used for long-term energy storage and are hydrophobic.

Front

What is the significance of the lipid bilayer in cell membranes?

Back

The lipid bilayer forms the fundamental structure of cell membranes, providing a barrier that separates the interior of the cell from the external environment.
