Fate of pyruvate produced by glycolysis depends on cellular needs, it can enter

1.	Lactic acid fermentation	2.	Alcoholic fermentation
3.	Aerobic respiration	4.	All are correct

In ETS, complex V is

1. ATP synthase
2. NADH dehydrogenase
3. Cytochrome c oxidase
4. Cytochrome bc${}_1$ complex

If RQ is 0.6 in a respiratory metabolism, it would mean that

1. Carbohydrates are used as respiratory material

2. Organic acids are used as respiratory substrate

3. The oxidation of the respiratory substrate consumed more oxygen than the amount of CO${}_2$ released

4. The oxidation of respiratory substrate consumed less oxygen than the amount of CO2 released

The process used in conversion of Pyruvate to Acetyl CoA is

1. Oxidative dehydration

2. Oxidative decarboxylation

3. Oxidative phosphorylation

4. Reductive phosphorylation.

When tripalmitin is used as substrate in respiration, the value of RQ is found to be less than one because

of glucose 
2. Net gain 38 ATP         -  Net gain 2 ATP.
3. Vigrously                   - NADH oxidised slowly
4. CO₂ released              - No CO₂ released.

RQ of tripalmitin is

1. $\frac{6{\mathrm{CO}}_2}{6{\mathrm{O}}_2}$

2. $\frac{102{\mathrm{CO}}_2}{145{\mathrm{O}}_2}$

3. $\frac{2{\mathrm{CO}}_2}{\mathrm{Zero} {\mathrm{O}}_2}$

4. $\frac{4{\mathrm{CO}}_2}{1{\mathrm{O}}_2}$
