Explain the similarities and differences in anaerobiotic and aerobic cellular respiration. 8 mark SL Answers must include twain(prenominal) similarities and differences to receive salutary moon about marks. * aerobic requires type O and anaerobic does not utilize oxygen similarities: 3 max * both can set-back with glucose * both utilise glycolysis * both amaze ATP/energy(heat) * both produce pyruvate * carbon dioxide is produced * (both start with glycolosis) aerobic leads to Krebs cycle and anaerobic leads to unrest 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 * advertise oxidise to CO2 and water (in Krebs cycle) * produce a immenser junction of ATP (36-38 ATP)/anaerobic produces less ATP ( 2) * can design 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 next structures clearly pinched and labelled correctly.
* outer tissue layer * intermembrane distance / outer compartment * informal membrane * hyaloplasm * cristae * ribosome * tender / invoice DNA * ATP synthase Do not accept germ plasm membrane. 5. Explain how the structure of the mitochondrion allows it to carry out its pilot the coop efficiently. 8 marks HL * membrane s to compartmentalise / name from processes! in the cytoplasm * vitiated size gives large bug out are to volume ratio * large surface population 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 scene of action * large surface area gives more space for...If you want to get a wide essay, order it on our website:
