BIOLOGY 151 Lecture Notes - Lecture 16: Acetyl-Coa, Pyruvate Dehydrogenase, Acetyl Group
Document Summary
Oxidaion- loss of electrons and decrease in electron density. Reducion- gain of electrons/ increase in electron density: o-o h2o is reducion. Cellular respiraion- aerobic and converts pyruvate into h20 , co2, and atp. (highest atp yields) Fermentaion- anaerobic and converts pyruvate into lacic acid or ethanol, co2, and atp. Cellular respiraion completely oxidizes and you get about 32 atp while geing 2 atp in fermentaion. Co2 is the least reacive form of carbon. The ive metabolic pathways occur in diferent parts of the cell. In cytoplasm or plasma membrane is where plant cells have metabolic reacions. In eukaryotes- mitochondria, glycolysis and fermentaion is where these energeic reacions occur. Glycolysis- series of reacions that make atp from parial breakdown of sugar into energy. If oxygen is not present, we refer to fermentaion once glycolysis is done. Glycolysis can not coninue unil you regenerate nad+ We needed 2 nad+ to form 2 nadh + 2h^+.
