Solution

The correct option is D
Both assertion and reason are correct

During respiration, glucose molecule, a 6-carbon compound, breaks down into two molecules of a 3-carbon compound called pyruvate. Glycolysis or breakdown of glucose takes place in the cytoplasm of cell and pyruvate breaks further in mitochondria, forming carbon dioxide and energy.
