Krebs Cycle Flashcards
1
Q
Why is their less o2 uptake when kerbs cycle is inhibited
A
- less NADH and coenzymes produced
- o2 is final acceptor electron
2
Q
What happens in the krebs cycle
A
-acetylene coenzyme A (2c) reacts with (4c) molecule
- releasing coA
- producing a 6c molecule that enter the Krebs cycle
- 4c molecule is regenerated and
- Series of redox reactions produces
- ATP by substrate levels phosphorylation
- reduced FAD and NAD
- 2x co2 lost
3
Q
Products produced per glucose molecules in Krebs cycle
A
Useful - 6 x NADH 2 x FADH 2 x ATP
Waste - 4 x co2
4
Q
Where does the krebs cycle occur
A
Mitochondrial matrix
