- Competitive Inhibition
- a m. wt. 10^3- 10^9; nucleic acids, proteins, lipids, polysaccharides. 4 most important to study.
- b Sugar + Base
- c occupy the active site
- d antiparallel orientation of complimentary strands; DNA is supercoiled in the cells; denaturation and renaturation. ssDNA absorbs more light. RNA can compete with ssDNA hybridization.
- e The localized twisting and folding of the polypeptide chain. A specific orientation in space. Two main types: the alpha helix and the beta sheet. Helix- parallel some of the strongest; alpha keratin-nails; spiderwebs. Pleated sheet- anti-parallel; Beta keratin- silk. 18% of all proteins are one of these two shapes; others are random coiling
5 Multiple choice questions
- one or more double bonds (mostly between 9 and 10); Plant and animals in cold climates.
- glucose and fructose; bad for teeth
- 10s-100s of polysaccharides; storage molecules, i.e., cellulose, chitin, glycogen; linear or branched; made of similar or different subunits.
- DNA and RNA; Basic Unit- nucleotide; Building Blocks- a cyclic pentose sugar; phosphate; nitrogenous base. DNA lacks a hydroxyl group making it more flexible.
- proteins and RNA
5 True/False questions
Topoisomerases → alters the topology of DNA molecules.
Nucleotide → Sugar + Base
Saturated → one or more double bonds (mostly between 9 and 10); Plant and animals in cold climates.
Lactose → glucose and galactose
Ketose → fruit sugar mostly; but found in plants and animals also
