Front

What is the primary function of carbohydrates?

Back

The primary function of carbohydrates is to provide energy and support cellular structure.

Front

What are lipids and their primary functions?

Back

Lipids are hydrophobic molecules that store energy, provide insulation, and make up cell membranes.

Front

What are proteins made of?

Back

Proteins are made of amino acids, which are linked together by peptide bonds.

Front

What is the role of enzymes in biological processes?

Back

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

Front

What are nucleic acids and their functions?

Back

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

Front

What is the structure of a nucleotide?

Back

A nucleotide consists of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the difference between saturated and unsaturated fats?

Back

Saturated fats have no double bonds between carbon atoms and are solid at room temperature, while unsaturated fats have one or more double bonds and are liquid at room temperature.

Front

What is the function of proteins in the body?

Back

Proteins serve various functions, including structural support, transport, communication, and catalyzing biochemical reactions.
