Results of GlycolysisVII. FermentationVIII. MitochondriaCurrent LectureI. Electron Carriersa. Electrons shared between atoms in covalent bondsb. Covalent bonds broken, electrons free to interact with other atomsc. Substrate is reducedi. Gains :H- , other proton is released (H+) into aqueous solutionii. RIG – reduction is gainedd. Accept electrons released from catabolic reactionse. Donate electrons to other substratesII. NAD+a. Nicotinamide adenine dinucleotideb. Building Block: Niacinc. Figure 7.4III. FADa. Flavin Adenine Dinucleotideb. Building Block: riboflavinIV. Glycolysisa. Locationi. Eukaryotic Cells1. Cytosolii. Prokaryotic Cells1. Cytosolb. Watch the MasteringBio vid of cellular respirationV. Reactions of Glycolysisa. Know the chartb. Reactant is glucose, 2 NAD+, 2 ATP c. Produces, 2 pyruvate, 4 ATP, 2 NADHd. Glucose Glucose 6 Phosphate intermediate pyruvateVI. Results of Glycolysisa. Occurs in cytosolb. Glucose 2 pyruvate + H2Oc. In presence O2i. Pyruvate is transported into mitochondria and oxidizedVII. Fermentationa. In absence of O2, fermentation occurs in cytosoli. Pyruvate accepts electrons from NADHii. Regenerates NAD+ iii. Glycolysis continuesVIII. Mitochondriaa. Contain own DNAb. Contain own ribosomesc. Location of i. Citric acid cycleii. Electron transportiii. ATP production (oxidative
