BIOL 1210 Lecture Notes - Lecture 1: Facilitated Diffusion, Citric Acid Cycle, Cytoplasm
Document Summary
What can persist- gene pool (mixture of all genetic info and gene frequency) Pyruvate ---> lactate (which is waste and excreted but used by other cells) Final acceptors become initial donors in etc. Aerobic respiration: oxygen is available and used as the final acceptor. Anaerobic: oxygen isn"t the final acceptor and not present. Focus on: (a)structure, (b)how made, and (c)role. How dna(abc) plays a role in making proteins(abc), how proteins play a role in making. Options: can make it from environment, or get it from environment. Has to cross membrane- simple diffusion, facilitated diffusion, active transport. Further rearrangement: metabolic pathways (where processors are enzymes) Metabolic pathways: calvin cycle, nitrogen fixation, glycolysis, krebs cycle. A constant flow of electrons and phosphates. Parts of the cycle are in all. Sphere- least amount of surface per volume for any shape. Why cells aren"t shaped like a bubble. Surface area has to keep up with volume. Three spaces- defining aspect of eukaryotic cells.
