CELLULAR RESPIRATION Metabolism—the sum of all biochemical reactions in an organism or cell. a) anabolic—synthesis of compounds; an example is photosynthesis b) catabolic—breakdown of compounds; an example is cellular respiration Metabolic pathways—are the steps (enzymes, substrates and products) used or followed to convert one substance to another. example: 2 metabolic pathways can be followed for the oxidation (or breakdown) of glucose—Anaerobic (no O2) or aerobic (O2 present) respiration Fates of Pyruvate from glycolysis (2/glucose) Pyruvate anaerobic yeast NADH , H+ + NAD anaerobic muscle NADH , H+ pyruvate dehydrogenase complex NAD+ Ethanol + CO2 2 ATP Lactate 2 ATP Acetyl COA Citric Acid Cycle Electron Transport 36 ATP Overall Eqn. for anaerobic respiration: a) glucose 2 ethanol + 2 CO2 + 2ATP (commercial use: beer & wine) b) glucose 2 lactic acid + 2ATP (commercial use: yogurt, cheese, sauerkraut, spoilage) Overall Eqn. for aerobic respiration: glucose (C6H12O6) + 6 O2 6 H2O + 6 CO2 glycolysis cell location pathways ATP Products Anaerobic yes all cytoplasm Aerobic yes cytoplasm glycolysis no no 2 mitochondria glycolysis Kreb’s/Citric Acid Electron transport 36 Ethanol + CO2 or Lactate CO2 +H2O Today’s lab: 1) Omit or demo of anaerobic respiration 2) Omit Thermo bottles w/ seeds 3) Omit CO2 gas released during respiration (CO2 + OH ppt.) 4) O2 consumption of Endotherms (organisms that generate own heat during respiration) at 10°C and room temperature. Calculate respiration rate and graph data. Using mice with CO2 absorber (ascarite) and water absorber (drierite) 5) O2 consumption of Ectotherms (organisms that rely more on environment for heat). Use data provided in lab manual to calculate respiration rates and graph.
