Back

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

Front

What are lipids?

Back

Lipids are a group of macromolecules that include fats, oils, and waxes, which are hydrophobic and store energy.

Front

What are nucleic acids?

Back

Nucleic acids are macromolecules made up of nucleotides, which include DNA and RNA, and are essential for storing and transmitting genetic information.

Front

What are proteins?

Back

Proteins are macromolecules made up of amino acids and are essential for various functions in the body, including catalyzing reactions as enzymes.

Front

What is the role of enzymes?

Back

Enzymes are proteins that act as catalysts to speed up chemical reactions in biological processes.

Front

What is commensalism?

Back

Commensalism is a type of symbiotic relationship where one organism benefits while the other is neither helped nor harmed.

Front

What is the structure of carbohydrates?

Back

Carbohydrates are composed of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1.

Front

What is the function of lipids in the body?

Back

Lipids serve as long-term energy storage, insulation, and make up cell membranes.
