Question

1. choose the best answer. what is a macromolecule? an amino acid a small molecule an enzyme a big molecule 11) choose all that apply. what are the four macromolecules that are important to life? lipids (fats and oils) nucleic acids carbohydrates hydrogen proteins oxygen

Explanation:

A macromolecule is a very large molecule, often formed by polymerization of smaller subunits. The four major macromolecules important for life are lipids, nucleic acids, carbohydrates, and proteins. Hydrogen and oxygen are elements, not macromolecules. An amino - acid is a building block of proteins, a small molecule by itself. An enzyme is a type of protein (a macromolecule), but not all macromolecules are enzymes. A small molecule is the opposite of a macromolecule.

Answer:

1. D. a big molecule
2. A. lipids (fats and oils), B. nucleic acids, C. carbohydrates, E. proteins
