5 Matching questions
- metabolic intermediates
- Feedback Inhibition
- Supra Molecular Assemblies
- a most important are disaccharides; covalent linkages of two monosaccharides with the release of H2O (glycosidic bond). i.e. sucrose, lactose, maltose, etc.
- b pyruvate, citrate, malate, etc.
- c End-product allosterically inhibits the action of first enzyme in pathway. prevents cell from wasting resources.
- d m. wt. = 10^6-10^9; ribosomes, enzyme complexes, contractile systems, microtubules.
- e proteins and RNA
5 Multiple choice questions
- can be done with RNA or ssDNA
- Usually polymers; usually dehydration synthesis also called condensation rxn.
- m. wt. 10^3- 10^9; nucleic acids, proteins, lipids, polysaccharides. 4 most important to study.
- antiparallel orientation of complimentary strands; DNA is supercoiled in the cells; denaturation and renaturation. ssDNA absorbs more light. RNA can compete with ssDNA hybridization.
- diagnostic technique; denature and add a known fluoresced DNA. Don't have to know base structure.
5 True/False questions
Lipids → glucose and galactose
RNA → Mostly single stranded; uracil in place of thymidine; mRNA; rRNA, tRNA
Maltose → glucose and galactose
Ketose → glucose and galactose
Secondary → The overall 3D structure of the polypeptide chain. Held together by different bonds: peptide, ionic, hydrogen, covalent, sulfhydryl, etc. Prions are proteins that don't take their correct 3D shape and are harmful; mad cow disease.
