Question

which of the following is not a function of biological molecules? energy storage instructions for heredity material create salts needed for electrical signaling essential sources of energy rewatch

Explanation:

1. Analyze each option:

• Energy storage: Molecules like carbohydrates (e.g., glycogen) and lipids store energy, so this is a function.
• Instructions for heredity material: Nucleic acids (DNA, RNA) carry genetic instructions, so this is a function.
• Create salts needed for electrical signaling: Biological molecules (like proteins, nucleic acids, carbohydrates, lipids) do not create salts for electrical signaling. Salts (ions) for electrical signaling (e.g., in neurons) come from inorganic sources or ion channels regulating ion movement, not being created by biological molecules.
• Essential sources of energy: Carbohydrates, lipids, and proteins can be energy sources, so this is a function.

Answer:

create salts needed for electrical signaling
