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.
