Question

Which one of the following statements is NOT CORRECT?

• A. Respiration is the process of the exchange of gases between the lungs and the atmosphere
• B. Breathing is an extracellular process
• C. Energy is used in the process of breathing
• D. Several enzymes are involved in the process of respiration

Answer 1

The correct option is A Respiration is the process of the exchange of gases between the lungs and the atmosphere

Breathing is the process of exchange of gases between the lungs and the atmosphere in which oxygen rich air from the atmosphere is taken into the lungs and carbon dioxide rich air from the lungs is released into the atmosphere.
Respiration is the process in which the food is oxidized to form carbon dioxide, water, and energy. In the process of cellular respiration, several cytoplasmic and mitochondrial enzymes are used to break down the complex biomolecules from food efficiently. Breathing is an extracellular process as it occurs outside the cells. In the process of breathing, contraction of muscles in diaphragm, intercostal muscles and abdomen takes place which consumes energy.
