5C sugar, N2 base, Phosphate group
DNA/RNA
4
carbohydrates
nucleic acids
catalyst - starts, stops, speeds up or slows down a chemical reaction without
becoming part of the reaction
organic catalyst = enzyme
a. carbohydrate
b. protein
c. lipid
d. nucleic acid
polysaccharide/glycogen
X = substrate/reactant
Y = enzyme/active site
Z = products
enzyme doesn't change
it changes it so the active site no longer fits the substrate
amino acids
True
Nucleic acid, protein, lipid
chemical reactions
Carbohydrates - C,H,O (1:2:1)
Lipids - C,H, and a little O
protein - C,H,O,N
nucleic acids - C,H,O,N,P
carb = E source
Lipid = water loss, insulation, membranes, E storage
protein - controls cell function
nucleic acid - transmit genetic info
"many units" - long chains of monomers
monosaccharide = glucose
proteins
speed up, start, stop organic reactions; an organic catalyst
peptide chain, polypeptide, dipeptide, peptide bond, protein
glucose - glycogen or monosaccharide - polysaccharide
fatty acid and glycerol - fatty acid chain
amino acid - polypeptide
nucleotide - DNA/RNA
organic catalyst
