Current Question (ID: 11571)

Question:

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

Options:

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.

Solution:

The RQ (respiratory quotient) is the ratio of the amount of carbon dioxide produced to the amount of oxygen consumed during respiration. For tripalmitin, which is a lipid composed of three palmitic acid molecules, the complete oxidation requires a large amount of oxygen, resulting in a high oxygen consumption rate. The amount of carbon dioxide produced is relatively less, resulting in an RQ value less than one.
