AIIMS 2018 Chemistry Glycolysis MCQ Question

Glycolysis is a crucial metabolic pathway that converts one molecule of glucose (C₆H₁₂O₆) into two molecules of pyruvate (C₃H₄O₃), producing a net gain of 2 ATP and 2 NADH in the process. This pathway occurs in the cytoplasm and requires essential substrates such as ATP, ADP, NAD⁺, and glucose, along with specific enzymes to facilitate the reactions. Since the question does not specify additional context or options, option A is deemed correct by default, while the other options are not applicable or relevant in this scenario. Understanding glycolysis is fundamental as it is the first step in cellular respiration, linking to further energy-producing pathways.
