Tobacco consumption is known to stimulate secretion of adrenaline and nor-adrenaline. The component causing this could be:

a. Nicotine

b. Tannic acid

c. Curamin

d. Catechin

Answers (1)

The answer is the option (a) Nicotine

Explanation: Nicotine, the primary active ingredient in tobacco, is responsible for triggering the release of adrenaline and nor-adrenaline in the body. These hormones are involved in the body's "fight-or-flight" response, leading to increased heart rate, elevated blood pressure, and other physical changes associated with heightened stress or alertness.

Explanation for the incorrect options: 

  • b. Tannic acid: A polyphenol present in tea and other plants, tannic acid does not stimulate the release of adrenaline or nor-adrenaline.
  • c. Curamin: Derived from turmeric, curamin is known for its anti-inflammatory effects but has no impact on the secretion of these hormones.
  • d. Catechin: Another polyphenol found in tea with antioxidant properties, catechin does not influence adrenaline or nor-adrenaline levels.
