Question

The oxidation of glucose to two molecules each of pyruvate, ATP, and NADH is called .......... and occurs in the ..........
Options
A glycolysis; cytoplasm
Correct Answer
B fermentation; cytoplasm
C the Krebs cycle; matrix of the mitochondrion
D anaerobic respiration; cytoplasm
Correct Answer

Option A is the correct answer.

Detailed Explanation

The process described is glycolysis. It is the first stage of cellular respiration, where one molecule of glucose (6C) is broken down into two molecules of pyruvate (3C). This process occurs in the cytoplasm (cytosol) of the cell and produces a net gain of 2 ATP and 2 NADH.

Hint

This universal pathway breaks down glucose in the cell's main fluid.
