Respiratory Quotient.
Respiratory substances.
Respiratory organelles.
Respiratory substrates.
3)
What is the most preferred respiratory substrate among the below options?

4)
What will be the respiratory quotient if carbohydrates used as a respiratory substrate?
2
0.7
0.75
1
5)
Why is the rate of respiration less in fat and protein containing foods when compared to carbohydrate containing foods?
The fats and proteins contain fewer oxygen atoms than carbon atoms in their molecules.
The fats and proteins contain more oxygen atoms than carbon atoms in their molecules.
The fats and proteins contain equal amounts of oxygen atoms and carbon atoms in their molecules.
Fats and proteins contain fewer oxygen atoms than hydrogen atoms in their molecules.
