8.2 Cell Respiration IBDP Biology HL

8.2 Cell Respiration IBDP Biology Higher Level

Chapters:
00:00 Cell respiration involves the oxidation and reduction of electron carriers
06:12 Phosphorylation of molecules makes them less stable
07:38 In glycolysis, glucose is converted to pyruvate in the cytoplasm
08:40 In aerobic cell respiration pyruvate is decarboxylated and oxidized, and converted into acetyl compound and attached to coenzyme A to form acetyl coenzyme A in the link reaction
12:19 In the Krebs cycle, the oxidation of acetyl groups is coupled to the reduction of hydrogen carriers, liberating carbon dioxide
16:48 Energy released by oxidation reactions is carried to the cristae of the mitochondria by reduced NAD and FAD
18:14 Transfer of electrons between carriers in the electron transport chain in the membrane of the cristae is coupled to proton pumping
26:28 Structure of mitochondria and endosymbiosis hypothesis
28:21 Summary
