Nucleotides.

Front

What is the primary function of lipids in biological systems?

Back

Energy storage, insulation, and making up cell membranes.

Front

What is the difference between saturated and unsaturated fatty acids?

Back

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

Front

What role do enzymes play in biochemical reactions?

Back

They lower the activation energy required for reactions to occur.

Front

What is the structure of a nucleotide?

Back

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

Front

What are the four main types of biological macromolecules?

Back
