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

Hint: Floating respiration is a type of cellular respiration or exchange of gases. In the process of cellular respiration, the food materials are stored in the protoplasm in which oxidized pods of energy are called fuels of the cell or respiratory substrates are called yielding foods.

Complete answer:
Floating respiration is a type of cellular respiration or exchange of gases through which utilizes the carbohydrates or fats as the substrate for their respiration. The substrate is usually obtained from the storage materials in which they get hydrolyzed. Floating respiration makes the cells healthier and they do not produce any toxic by-products. When fats and carbohydrates are used as respiratory fuel are floating respiration and protein is used as protoplasmic respiration.

Floating respiration is a type of respiration in which any nutrients like fats and carbohydrates, are taken outside the cell or body and are digested. The respiration of fats and carbohydrates is named floating respiration because their substrates are usual storage food reserves of the body and not the structural components of the body like the proteins.

In the process of cellular respiration, the food materials are stored in the protoplasm in which oxidized pods of energy are called fuels of the cell or respiratory substrates are called yielding foods. The chief fuel is glucose; it is the easiest available as well as utilizable food for most cells. But fats and protein may also be utilized in respiration.

Hence, the correct answer is option (C).

Note: Respiration may also include breathing and cellular respiration. The glucose directly enters glycolysis, which is the first phase of respiration. Other sugars can also enter the citric acid cycle is the second phase of respiration. At last, the end products are carbon dioxide and water, it occurs in the living cells and it is the most common type of respiration.
