Question

Respiration can be defined as

• A. A catabolic process by which animal cells utilise carbon dioxide, produce oxygen and convert the released energy to ATP
• B. A catabolic process by which animal cells utilise oxygen, produce carbon dioxide and convert the released energy to ATP
• C. An anabolic process by which animal cells utilise oxygen and carbon dioxide to form ATP
• D. An anabolic process by which animal cells utilize oxygen, produce carbon dioxide and convert the released energy to ATP

Answer 1

The correct option is B A catabolic process by which animal cells utilise oxygen, produce carbon dioxide and convert the released energy to ATP

The series of metabolic processes by which living cells produce energy through the oxidation of organic substances is called cellular respiration. During the cellular respiration, the complex molecules break into a simpler substance to release energy in form of ATP. It is a aerobic reaction which takes place in the presence of oxygen.

So, the correct answer is option B.
