Two statements are given below and they are labelled as

Solution

Assertion (A): Adrenaline hormones are also called emergency hormones. Reason (R): Adrenaline increases metabolism of carbohydrates to provide instant energy. The assertion (A) is correct. Adrenaline is often referred to as an emergency hormone because it is released in response to stress or danger, preparing the body for the "fight or flight" response. The reason (R) is also correct. Adrenaline does increase the metabolism of carbohydrates. It stimulates the breakdown of glycogen (stored form of carbohydrates) into glucose, providing a quick source of energy to the body in response to the perceived emergency. Both the assertion and reason are accurate, and the reason explains why adrenaline is associated with emergency situations. Therefore, the correct answer is that the assertion (A) is true, and the reason (R) is the correct explanation of the assertion.
