Question

Adaptation to low temperature and freezing in animals occurs due to the production of

• A. Proline
• B. Analine
• C. Antifreeze proteins
• D. Antifreeze monosaccharides

Answer 1

Answer: (C)

Antifreeze proteins are proteins that are formed as an adaptation in animals to help them survive in cold regions. At low temperatures, ice crystals are formed in the cell which results in the death of the organism. Antifreeze proteins prevent ice crystal formation by reducing the metabolic rate of that animal hence enabling its survival. Thus the correct answer is option C.
