Respiration in Plants

Question:

Assertion:  The process of glycolysis is also known as the EMP pathway.
Reason: Glycolysis is the only process of respiration in aerobic organisms.

Options:

Both Assertion (A) and Reason (R) are true and Reason (R) is a correct explanation of Assertion (A).

Both Assertion (A) and Reason (R) are true but Reason (R) is not a correct explanation of Assertion (A).

Assertion (A) is true and Reason (R) is false.

Assertion (A) is false and Reason (R) is true.

Correct Answer:

Assertion (A) is true and Reason (R) is false.

Explanation:

The correct answer is Option (3) - Assertion (A) is true and Reason (R) is false.

Glycolysis is also known as the EMP pathway, as it was discovered by three German scientists-Gustav Embden, Otto Meyerhof, and J. Parnas in 1930.

In glycolysis, partial oxidation of glucose takes place that form two molecules of pyruvic acid. It occurs in the cytoplasm of the cell and is present in almost all living organisms.

Aerobic respiration consists of different processes i.e., (i) glycolysis, (ii) oxidative decarboxylation of pyruvic acid, (iii) Krebs’ cycle, and (iv) terminal oxidation and oxidative phosphorylation.

In anaerobic organisms, it is the only process in respiration. Glycolysis occurs in the cytoplasm of the cell and is present in all living organisms. In this process, glucose undergoes partial oxidation to form two molecules of pyruvic acid.
