+ WHAT are Macro. Molecules? ? ? Molecules made of Carbon = Organic n.

+ WHAT are Macro. Molecules? ? ? Molecules made of Carbon = Organic n. Make up all living things n. They are large (macro) n. There are 4 of them: 1. Carbohydrates 2. Lipids 3. Proteins 4. Nucleic Acids n. They are composed of varying amounts of C, H, O, N
