When Sucinyl CoA is converted to Succinate what molecule is created. How is this beneficial for energy production? | GTP is made, This can be converted to ATP in the following reaction. GTP+ADP-->ATP+GDP |
What enzyme does oxaloacatate stimulate? | Citrate synthase |
Define Anaplerosis and Cataplerosis. | Anaplerosis: the gain or regeneration of TCA intermediates from external sources. Cataplerosis: the reduction of TCA intermediates to external sources. |
Cataplerosis increases/decreases during exercise. It is/isn't the reason for fatigue, explain why. | Increases, isn't the reason for fatigue because although intermediates drop they never fall below the level of inactivity levels. |
Name the rate limiting enzyme in TCA cycle. | Isocitrate dehydrogenase |
What is the total yield of NADH, FADH, CO2 and GTP from one cycle of the TCA cycle? | 3 NADH, 1 FADH, 2 CO2, 1 GTP (which forms one ATP) Remember however that from one glucose molecule we generate two acetyl-CoA molecules so the TCA cycle can go round twice from one glucose. |
Give the 9 intermediates of the TCA cycle | Acetyl CoA, Citrate, Iso Citrate, Alpha Ketoglutimate, Sucinyl CoA, Succinate, Fumerate, L-Malate, Oxaloacetate |
