Question

Which of the following activity is catabolic in nature?

• A. Cell repair
• B. Protoplasm synthesis
• C. Degradation of amino acid in liver
• D. Conversion of glucose to glycogen

Answer 1

Answer: (C)

Degradation of amino acid in liver

Catabolism involves the breakdown of a substance, often to release energy or during excretion for removal of waste. Degradation of amino acids in the liver is such an example where amino acids are broken down into inorganic substituents for recycling or removal.

Cell repair, protoplasm synthesis and conversion of glucose to glucose are all examples of anabolism which involves the synthesis of a product.

So the correct answer is 'Degradation of amino acids in the liver'.
