Respiration Ib Questions

rationalise the similarities and differences in anaerobiotic and aerophilous cellular respiration. 8 marks SL Answers must take two(prenominal) similarities and differences to receive salutary moon on marks. * aerobic requires oxygen and anaerobiotic does not utilize oxygen similarities: 3 max * two can transposition with glucose * both utilise glycolysis * both develop adenosine triphosphate/energy(heat) * both produce pyruvate * carbon dioxide is produced * (both decease with glycolosis) aerobic leads to Krebs daily round and anaerobiotic leads to fermentation differences: 5 max anaerobic: * (fermentation) produces lactic acid in humans * (fermentation produces ethanol and CO2 in yeast * occurs in cytoplasm of the cell * recycles NADH (NAD+) aerobic cellular respiration * pyruvate transported to mitochondria * further alter to CO2 and water (in Krebs cycle) * produce a immenser join of adenosine triphosphate (36-38 ATP)/anaerobic produces less ATP (2) * can use different compounds / lipids / amino acids for energy 4.
