Vedclass · Answer

(A) Adrenaline is an emergency hormone,also known as the fight-or-flight hormone,which is secreted by the adrenal medulla during stress conditions such as intense cold,fear,or anger.Adrenaline increases the metabolic rate by stimulating glycogenolysis (breakdown of glycogen to glucose) and increasing oxygen consumption,which helps in thermogenesis (heat production) to maintain body temperature in cold conditions.Therefore,the secretion of adrenaline in intense cold is a physiological response to increase the metabolic rate and generate heat.Thus,both the Assertion and the Reason are correct,and the Reason is the correct explanation of the Assertion.

Assertion : Our body secretes adrenaline in intense cold.
Reason : Adrenaline raises metabolic rate.
