Energy II: Acetyl CoA, Mitochondria, Oxygen Flashcards
1
Q
Explain Aerobic respiration
A
-Occurs only in the presence of oxygen -Yields more energy in the form of ATP -Requires the citric acid cycle and oxidative phosphorylation -Takes place in the mitochondria
2
Q
In the citric acid cycle, what is produced for each glucose?
A
6 NADH + 2 NADH 2 FADHsq 2GTP 4CO2 + 2CO2
3
Q
What makes acetyl co-enzyme A?
A
Fatty acids and proteins
4
Q
Where does the citric acid cycle take place?
A
In the mitochondrial matrix
5
Q
What is not produced in the citric acid cycle?
A
ATP
6
Q
What is formed per citric acid cycle?
A
1 GTP, 3 NADH and one FADHsquared
7
Q
Formation of acetyl CoA from pyruvate is…
A
Irreversible
8
Q
Explain the formation of Acetyl CoA…
A
- enzyme is pyruvate dehydrogenase
- Pyruvate 3C —-> Acetly CoA 2C + NADH + CO2
- Inhibited by NADH and Acetyl CoA
- Also regualted through phosphorylation by a kinase and a phosphatase
9
Q
A
