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 CO2 released

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

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

1. It contains less number of carbon atoms than oxygen atoms.
2. The amount of CO2 evolved is more than the amount of O2 consumed.
3. The amount of O2 consumed is more than the amount of CO2 evolved.
4. The ratio of the numbers of carbon and hydrogen atoms in this molecule is not 1 : 2.
