17 (19.3) - TCA Cycle Flashcards
1
Q
Pyruvate (3C compound) oxidized into… (+what’s lost?)
A
acetate+CoA (enzyme)
lost co2
2
Q
What’s the first thing in the TCA cycle
A
The acetyl CoA from pyruvate
3
Q
Aerobic or anaerobic
A
Aerobic
4
Q
Where? How does pyruvate get there?
A
Cytosol of Mitochondria, via active transport (bc its charged) with help of a transport protein
5
Q
Products?
A
ALOT of NADH
A little FADH2
NOT a lot of energy, but lots of electron carriers
6
Q
What is lost from pyruvate to acetyl CO-A
A
Lose (CO2) from breaking pyruvate’s carboxyl group
The above produces 2ATP
Lose (NADH + H+) also
7
Q
The reaction of acetyl CO-A to yield lower energy products is
A
Exergonic
8
Q
What kind of phosphorylation
A
Substrate level
9
Q
Products of TCA from 2 pyruvate (1 glucose)
A
8NADH, 2FADH2, 2ATP, 3CO2
