What is an amino acid?

It is the monomer of a Protein.

6

What is the function of a carbohydrate?

Provides energy and play a huge STRUCTURAL and STORAGE role within cells.

How are lipids different from other organic molecules?

They are relatively smaller and do not have a monomer or polymer.

-They are partially or fully hydrophobic.

19

What is a polypeptide?

The polymer of protein, or the a chain of amino acids.

20

This moldecule can act as storage, a receptor, enzymes, muscle contractions:

6 electrons, 2 on inner, 4 on outer.

22

WHat are macromolecules and name them?

They are a large complex organic molecule composed of many repeated subunits.
These are of the four major organic molecules and include Carbs, Nucleic acids, and proteins.

23

What functions do phospholipids serve?

Make up the cell membrane and help keep things out but are SELECTIVELY PERMEABLE.

Cholesterol
and
Sex Hormones.
