Q
ATP acts in fpk
A
Regulatory
1
Q
High ATP conc causes
A
ATP to bind at the regulatory site
Changing the enzyme shape
Decreasing the reaction rate at the active site
2
Q
Glycolysis produces
A
- transported from the cytosol
- into mitochondria
3
Q
Cristae
A
- are layers of sac-like structure
- fill the interior of the mitochondria
- are connected to the inner membrane
4
Q
Mitochondrial matrix
A
Inside inner membrane
Outside cristae
5
Q
Pyruvate processing
A
The second step in glucose oxidation
Catalyzed by the enzyme Pyruvate dehydrogenase
In the mitochondrial matrix
Under both positive and negative control
6
Q
Pyruvate in O2
A
Pyruvate undergoes a series of reactions. Product molecule acetyl coenzyme A.
NADH is synthesized
A Carbon oxidized to CO2
7
Q
Third step of glucose oxidation
A
The citric acid cycle
8
Q
Citric acid process
A
- acetyl CoA produced by Pyruvate processing enters cycle
- located in mitochondrial matrix
- each acetyl CoA is oxidized to two molecules of CO2
- reduce NAD to NADH
- reduce fad to fadh2
- phosphorylate GDP to form GTP converted to ATP
3NADH, 1FADH2, 1 GTP
