What are macromolecules?

Back

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

What is a carbohydrate?

Back

Carbohydrates are macromolecules made of carbon, hydrogen, and oxygen, and they serve as a primary energy source for living organisms.

Front

What is a lipid?

Back

Lipids are macromolecules that store energy, provide insulation, and make up cell membranes. Examples include fats and oils.

Front

What is a protein?

Back

Proteins are macromolecules made of amino acids that perform a variety of functions, including catalyzing reactions (enzymes), providing structure, and transporting molecules.

Front

What are nucleic acids?

Back

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

Front

What is a monomer?

Back

A monomer is a small, basic molecular unit that can join together to form larger molecules called polymers.

Front

What is a polymer?

Back

A polymer is a large molecule made up of repeating units (monomers) linked together, like a long chain.

Front

What is the primary function of carbohydrates?

Back

The primary function of carbohydrates is to provide energy for the body.

Front

How do macromolecules break down in the body?

Back

Macromolecules are broken down into their smaller components (monomers) during digestion, allowing the body to use them for energy or building blocks.

Front

What is the role of lipids in the body?

Back

Lipids store energy, provide insulation, and are key components of cell membranes.
