(7 cards)
1
Q
How does Acetyl CoA enter the Krebs Cycle?
A
Joins to 4C oxaloacetate.
2
Q
What does this form?
A
6C citrate.
3
Q
When citrate is decarboxylated, what are the products?
A
CO2 and 5C oxoglutarate.
4
Q
When oxoglutarate is decarboxylated, what are the products?
A
CO2 and 4C oxaloacetate.
5
Q
How many times in the cycle does dehydrogenation occur
A
- 3 reduce NAD to NADH, 1 reduces FAD to FADH2.
6
Q
At some point in the cycle, enough energy is released for what to occur?
A
Substrate level phosphorylation of ADP +Pi to ATP.
7
Q
How many ATP molecules are produced?
A
1 for each turn of the cycle. Per glucose, since 2 pyruvate molecules are produced, the cycle turns twice. 2 ATPs produced per glucose.
