Chapter E Flashcards
Complete oxidation of pyruvate happens in
Mitochondrial matrix
What is rate limiting step in CHO oxidation ?
Oxidation of pyruvate
In oxidation of pyruvate, pyruvate becomes —–with the help of pyruvate dehydrogenase
Acetyl CoA
Rate of citric acid cycle reduced if
CHO depleted
What is oxidative phosphorylation ?
The coupling of the electron transport chain to ATP synthesis via the proton gradient and ATP synthase
Uses energy released by oxidation of nutrients to generate ATP
T/F
Oxidative phosphorylation uses energy released by oxidation of nutrients to generate ATP
T
Oxidative phosphorylation is carried out by series of
Protein complexes in the mitochondria
“Chain “ in electron transport chain are
Adj enzymes
T/F
Oxygen is involved in > 90% of all ATP produced
T
Where does ETC occur
Mitochondria
% volume of cell occupied by mitochondria parallels need for
Oxidative phosphorylation in the cell
T/F?
Exercise training can increase mitochondrial volume up to 2 folds
T
Each ml of mitochondrial volume used up to how much O2 per minute
3-5 ml O2/ min
How many lipid complex on mitochondrial inner membrane ?
4 protein lipid complex
What are the functions of protein lipid complexses
Transfer electron to oxygen
