citric acid cycle
Question | Answer |
---|---|
what is the purpose of the citric acid cycle? | creates energy for the next part of respiration NADH and FADH2 are electron carriers made here draw out all remaining energy for pyruvate |
what kinds of reactions are in the citric acid cycle? | redox, dehydration, hydrolysis, decarboxylation |
citric acid cycle formula | 2 acetyl-CoA --> 2CO2 + 1 ATP + 3NADH + 1FADH2 |
acetyl-CoA --> citrate cannot be reversed because.... | it is highly exergonic |
citrate --> isocitrate involves.... | gain and loss of a water molecule |
regulatory reactions in citric acid cycle | reactions 3 and 4 are slowed by high NADH levels |
substrate level phosphorlation | 5. phosphate group swaps with CoA on succinyl-CoA, forming succinate and ATP |
how is CO2 formed? | carbon from breakdown of pyruvate |
what is the main energy carrier produced by citric acid cycle? | NADH |
