  21. C.2.4

  22. Prontosil is a competitive inhibitor that is used as an antibiotic because it inhibits folic acid synthesis in bacteria. Nerve gases like Sarin function by inactivating the enzyme ethanoyl (acetyl) cholinesterase.

  23. C.2.5

  24. 7.6.5

  25. C3, 8.1: Cellular Respiration

  26. C.3.1, 8.1.1:Oxidation/Reduction STATE: oxidation involves the gain of oxygen reduction involves the loss of oxygen

  27. C.3.1, 8.1.1: Oxidation/Reduction STATE: oxidation involves loss of electrons reduction involves gain of electrons

  28. C.3.1, 8.1.1:Oxidation/Reduction STATE: oxidation involves loosing hydrogen reduction involves gaining hydrogen

  29. C.3.1, OiLRiG ???????( OiLRiG only applies to electrons and hydrogen)

  30. (Aerobic)Cellular Respiration Formula GLUCOSE + OXYGEN CARBON DIOXIDE + WATER + ATP C6H12O6 + 6O2  6CO2 + 6H2O

  31. C.3.2, 8.1.2: Outline the process of glycolysis, including phosphorylation, lysis, oxidation and ATP formation

  32. 8.1.2: Glycolysis

  33. Adenosine triphosphate

  34. NAD: Electron CarrierNAD+ = oxidised form NADH + H + = reduced form NAD+ + 2H → NADH + H+

  35. 2 2 Oxidation of triose phosphate Reduction of NAD + to NADH + H + 2 2 Pyruvate Pyruvate

  36. From one glucose molecule in glycolysis: 2 x ATP (net) 2 X (NADH + H+) 2 X pyruvate

  37. IB Question: Outline the process of glycolysis. [5] occurs in cytoplasm; hexose is phosphorylated using ATP; hexose phosphate is split into two triose phosphates; oxidation by removal of hydrogen; (do not accept hydrogen ions/protons) conversion of NAD to NADH (+H+); net gain of two ATP / two ATP used and four ATP produced; pyruvate produced at the end of glycolysis; [5 max] Accept glucose/fructose/6C sugar instead of hexose. Accept 3C sugar/glyceraldehyde instead of triose.

  38. NAD: Nicotinamide adenine dinucleotide, abbreviated NAD A co-enzyme is a non-proteinchemical compound that is loosely bound to a protein and is required for the protein's biological activity.

  39. C.3.3, 8.1.3: Draw and label a diagram showing the structure of a mitochondria as seen in electron micrographs
