what role do proteins play in the cell?
proteins are important 'action' and structural molecules in the cell

protein does its job.
what are the building blocks of protein?
amino acids
what are the four classes of organic molecules?

another way to ask is...

2. nucleic acids
3. polysaccharides
4. lipids
what are the building blocks of each one of the macromolecules?
1. proteins -> amino acids
2. nucleic acids -> nucleotides
3. polysaccharides -> monosaccharides
4. lipids -> fatty acid, glycerol
