Explanation:
Detailed explanation-1: -The steps of glycolysis are as follows: Glucose gets phosphorylated by hexokinase, forming glucose-6-phosphate. This step requires one molecule of ATP.
Detailed explanation-2: -During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi–> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O).
Detailed explanation-3: -The correct answer is C. No net ATP are generated after glycolysis. Glycolysis occurs in the cytoplasm or cytosol of the cells and it does not require oxygen. However, in the process of glycolysis, the net end products are two pyruvates, two NADH, and two ATP.
