AIIMS 2014 Zoology Animal Physiology MCQ Question
The colour in the brown fat is due is
its larger capacity for generating heat
large number of mitochondria present
a high concentration of iron containing cytochrome pigments
presence of chromatophores
Correct Answer
Detailed Explanation
The correct answer is C) a high concentration of iron-containing cytochrome pigments. Brown fat is rich in these pigments, which are involved in the electron transport chain and play a crucial role in energy metabolism, giving the tissue its characteristic brown color. This coloration is largely due to the presence of cytochromes, which contain iron and are essential for the production of heat through non-shivering thermogenesis in brown adipose tissue.
