Question

The term, "floating respiration" is used when the respiratory substrate is

• A. Carbohydrates
• B. Fats
• C. Both A and B
• D. Protein

Answer 1

The correct option is C Both A and B

Respiration is defined as the process in which reduced substrates like carbohydrates, fats and proteins are oxidised to release energy and the intermediates produced in the process can be used for biosynthetic activity. When proteins are used as respiratory fuels, it is called as protoplasmic respiration. When fats and carbohydrates are used as respiratory fuel, it is called as floating respiration.

Therefore, the correct answer is option C.
