  Glycolysis does not require oxygen, so it can quickly supply energy to cells when oxygen is unavailable

ATP can directly power the cell’s activities.

Each molecule of glucose results in 2 molecules of pyruvic acid, which enter the Krebs cycle. So each molecule of glucose results in two complete “turns” of the Krebs cycle.]]> 2021-01-27 08:23:56 UTC https://padlet.com/jorgepastoriza1/uoivsxlu3w4ddvam1629221336/wish/1130432091 Energy Totals jorgepastoriza1 https://padlet.com/jorgepastoriza1/uoivsxlu3w4ddvam1629221336/wish/1130446702 For each molecules of glucose that enters respiration.

The complete breakdown of glucose through cellular respiration results in the production of 36 ATP molecules.  This represents about 36 percent of the total energy of glucose.  The remaining 64 percent is released as heat.]]> 2021-01-27 08:27:56 UTC https://padlet.com/jorgepastoriza1/uoivsxlu3w4ddvam1629221336/wish/1130446702 Electron Transport Chain jorgepastoriza1 https://padlet.com/jorgepastoriza1/uoivsxlu3w4ddvam1629221336/wish/1130465842 The electron transport chain uses the high-energy electrons from glycolysis and the Krebs cycle to convert ADP into ATP.

NADH and FADH2 pass their high-energy electrons to electron carrier proteins in the electron transport chain.

At the end of the electron transport chain, the electrons combine with H+ ions and oxygen to form water.

Energy generated by the electron transport chain is used to move H+ ions against a concentration gradient across the inner mitochondrial membrane and into the intermembrane space.

H+ ions pass back across the mitochondrial membrane through the ATP synthase, causing the ATP synthase molecule to spin. With each rotation, the ATP synthase attaches a phosphate to ADP to produce ATP. ]]> 2021-01-27 08:33:23 UTC https://padlet.com/jorgepastoriza1/uoivsxlu3w4ddvam1629221336/wish/1130465842 Krebs Cycle 2 jorgepastoriza1 https://padlet.com/jorgepastoriza1/uoivsxlu3w4ddvam1629221336/wish/1130520606 The link reaction happens in the mitochondrial matrix and generates acetyl CoA that will be assimilated into the Krebs cycle.]]> 2021-01-27 08:48:57 UTC https://padlet.com/jorgepastoriza1/uoivsxlu3w4ddvam1629221336/wish/1130520606 Krebs Cycle in Respiration jorgepastoriza1 https://padlet.com/jorgepastoriza1/uoivsxlu3w4ddvam1629221336/wish/1130529950 As with glycolysis, you do not need to know the names of the intermediates, just the overall results. The following diagram links glycolysis, via the link reaction, to the Krebs cycle and the final part: the electron transport chain.

Key points to remember about the Krebs cycle:
1. The acetyl group that enters the Krebs cycle is successively oxidised as it loses hydrogen atoms (and electrons).
2. The hydrogen atoms lost are picked up by hydrogen carriers, either NAD or FAD, which are themselves reduced. Both NAD and FAD are hydrogen acceptor coenzymes that can be reduced by accepting hydrogen.
3. The oxidation of the acetyl group is coupled with a loss of carbon dioxide (i.e. decarboxylation).
