**PCB3134 -- Spring 2023** **Exam-I study guide** **Topics:** 1. **Preview of Cell Biology** a. Some historical perspective b. Techniques used in biological inquiry c. Strands of biological inquiry 2. **Macromolecules I** d. Carbon and its Importance in biological chemistry e. Bonding, different types -- related to the strength of association f. Macromolecule synthesis -- directionality, monomers, activated monomers g. **Nucleic acids:** DNA *vs.* RNA composition, structure. Monomers, differences between nucleosides and nucleotides, base pairing, Chargaff's rule, Griffith S-R strain experiments 3. **Macromolecules II** h. **Proteins** -- monomers, amino acid composition - directionality of synthesis, primary, secondary, tertiary, and quaternary structures -- differences -- bonding i. **Enzymes: catalysts of life** i. Activation energy barrier ii. Catalyst properties iii. Enzymes: proteins and RNA iv. Induced fit model v. Irreversible and reversable regulation (activation, and inhibition) of enzymes 4. **Macromolecules III** j. **Polysaccharides:** monomers, structures, L- D- isoforms -- roles inside a cell (structural, and storage) example: Cellulose, Starch, glycogen, pectin and their presumable roles k. **Lipids:** types of lipids, their function, amphipathic properties
