TCA/Kreb’s Cycle Flashcards
1
Q
What is the main goal of the TCA Cycle?
A
To generate:
1) NADH
2) FADH2
2
Q
What enters the TCA Cycle?
A
Acetyl CoA
3
Q
In the TCA Cycle, Acetyl CoA will be converted to:
A
Citrate
4
Q
What is the rate limiting enzyme of the TCA Cycle?
A
Isocitrate Dehydrogenase
5
Q
What does Isocitrate Dehydrogenase do?
A
Converts Isocitrate to Alpha-Ketoglutarate
6
Q
During which step in the TCA Cycle is the FADH2 produced?
A
Succinate -> Fumarate
7
Q
Where is the FIRST NADH in the TCA Cycle Generated?
A
Isocitrate -> Alpha-Ketoglutarate
8
Q
Where is the SECOND NADH in the TCA Cycle Generated?
A
Alpha-Ketoglutarate -> Succinyl-CoA
9
Q
Where is the THIRD NADH in the TCA Cycle Generated?
A
Malate -> Oxaloacetate
10
Q
What stimulates the TCA Cycle?
A
ADP
11
Q
What inhibits the TCA Cycle?
A
1) ATP
2) NADH
3) FADH2
