Complete oxidation of pyruvate happens in

Mitochondrial matrix

2

What is rate limiting step in CHO oxidation ?

Oxidation of pyruvate

3

In oxidation of pyruvate, pyruvate becomes -----with the help of pyruvate dehydrogenase

Acetyl CoA

4

Rate of citric acid cycle reduced if

CHO depleted

5

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

6

T/F

Oxidative phosphorylation uses energy released by oxidation of nutrients to generate ATP

T

7

Oxidative phosphorylation is carried out by series of

Protein complexes in the mitochondria

8

"Chain " in electron transport chain are

Adj enzymes

9

T/F

Oxygen is involved in > 90% of all ATP produced

T

10

Where does ETC occur

Mitochondria

% volume of cell occupied by mitochondria parallels need for

Oxidative phosphorylation in the cell

12

T/F?
Exercise training can increase mitochondrial volume up to 2 folds

T

13

3-5 ml O2/ min

14

How many lipid complex on mitochondrial inner membrane ?

4 protein lipid complex

15

What are the functions of protein lipid complexses

Transfer electron to oxygen

16

Most ATP synthesized in mitochondria but used in

Cytosol
