Respiration Ib Questions

Explain the similarities and differences in anaerobiotic and aerobic cellular respiration. 8 label SL Answers must include two(prenominal) similarities and differences to receive salutary bootleg marks. * aerobic requires atomic number 8 and anaerobic does not utilize oxygen similarities: 3 max * both can set-back with glucose * both utilise glycolysis * both build ATP/energy(heat) * both produce pyruvate * carbon dioxide is produced * (both start with glycolosis) aerobic leads to Krebs cycle and anaerobic leads to ferment 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 * gain ground oxidise to CO2 and water (in Krebs cycle) * produce a immenser roast of ATP (36-38 ATP)/anaerobic produces less ATP (2) * can give other compounds / lipids / amino acids for energy 4.

Explain how the structure of the mitochondrion allows it to carry out its take flight the coop efficiently. 8 marks HL * membranes to compartmental! ise / specialize from processes in the cytoplasm * vitiated size gives large place are to volume ratio * large surface origination to volume ratio allows rapid ingestion / release of materials * matrix contains enzymes of the Krebs cycle / matrix carries out Krebs cycle * inner membrane invaginated / infolded / forms cristae to increase the surface ambit * large surface area gives more space for...If you want to get a unspoiled essay, order it on our website: BestEssayCheap.com
