Question

Assertion (A): During aerobic respiration, glucose (food) breaks down into ethanol and carbon dioxide, with the release of energy which gets stored in ATP molecules. On the other hand, during anaerobic respiration, glucose (food) breaks down into carbon dioxide and water with the release of energy which gets stored in ATP molecules.

Reason (R): Respiration is essential for life because it provides energy for carrying out all the life processes which are necessary to keep the organisms alive.

विकल्प

• Both A and R are true and R is correct explanation of the assertion.

• Both A and R are true but R is not the correct explanation of the assertion.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is false but R is true.

Explanation:

• Assertion (A) is false: It has the products of aerobic and anaerobic respiration reversed. Aerobic respiration produces carbon dioxide and water, while anaerobic respiration (in yeast) produces ethanol and carbon dioxide.
• Reason (R) is true: Respiration releases energy required for all life processes, making it essential for survival.
