Respiration Ib Questions

Explain the similarities and differences in anaerobiotic and aerobic cellular respiration. 8 mark SL Answers must include some(prenominal)(prenominal) similarities and differences to receive salutary moon around marks. * aerobic requires group O and anaerobic does not utilize oxygen similarities: 3 max * both can set-back with glucose * both utilise glycolysis * both induce 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 * nevertheless oxidise to CO2 and water (in Krebs cycle) * produce a immenser gather of ATP (36-38 ATP)/anaerobic pr oduces less ATP (2) * can drop other compounds / lipids / amino acids for energy 4. Draw the structure of a chondriosome as seen in an electron microscope. 5 marks HL demo 1 mark for each of the followers structures clearly pinched and labelled correctly. * outer tissue layer * intermembrane post / outer compartment * informal membrane * intercellular substance * cristae * ribosome * tender / orbitual DNA * ATP synthase Do not accept plasma membrane. 5. Explain how the structure of the mitochondrion allows it to carry out its navigate the coop efficiently. 8 marks HL * membranes to compartmentalise / fragment from processes in the cytoplasm * vitiated size gives large rear are to volume ratio * large surface creation to volume ratio allows rapid ingestion / release of materials * matrix contains enzymes of the Krebs cycle / matrix carries out Krebs cycle * inner membrane invaginated / info lded / forms cristae to increase the surface! subject field * large surface area gives more space for...If you want to get a abundant essay, order it on our website: BestEssayCheap.com
