Open in App
Solution
The correct option is B glycolysis
Glycolysis is common to both aerobic and anaerobic modes of respiration. It occurs in the cytoplasm. It is the first stage of breakdown of glucose in aerobic respiration and the only stage in glucose breakdown in anaerobic respiration.
It is the process of partial oxidation of glucose or a similar hexose sugar into 2 molecules of pyruvic acid (also known as pyruvate) through a series of 10 enzyme-mediated reactions releasing some energy (as ATP) and also producing NADH (reduced nicotinamide adenine dinucleotide).
