Carbohydrate, Lipid, Nucleic Acid, Protein, Enzyme Carbohydrate: Sugars and starches which body breaks down to glucose ● Structural function: cellulose and chitin ● Energy storage: amylose, amylopectin, glycogen ● Recognition molecules: glycoproteins and glycolipids Lipids: Fatty acids and their derivatives that are soluble inwater ● H and C and main components ● Fats ● Hydrophobic- thus help separate aqueous compartments ● Store energy (fats, oils, adipose) Protein: Mole...

1. replication of material: amount must double through division of both daughter cells (mitosis) + gametes (meiosis) 2. Storage of info: nucleus is the library or repository where genes may be checked out for use or stay on shelves 3. expression of info: DNA - transcription to either mRNA, rRNA, or tRNA - ribosome - translation - protein 4. variation through mutations: evolution 4 things the genetic flow of materials is dependent on 2. advantageous; poor health consequences; adva...
