Proteins- Amino Acids
Lipids- Glycerol and Fatty Acids
Nucleic Acids-Nucleotides
300
What are the 3 parts of the cell theory?
1. All living things are made of Cells
2. Cells are the basic unit of structure and function.
3. Cells come from pre-exisiting cells.

Explain how you would build a polymer and what must be removed in order for this process to occur.
You would link monomers together using dehydration synthesis. One monomer would lose a H+ and one would lose a OH- ion to form water so a bond could be made.
