Detailed explanation-1: -Phosphofructokinase speeds up or slows down glycolysis in response to the energy needs of the cell. Overall, glycolysis converts one six-carbon molecule of glucose into two three-carbon molecules of pyruvate.
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: -Recall that glycolysis produces two molecules of pyruvate (pyruvic acid). Pyruvate, which has three carbon atoms, is split apart and combined with CoA, which stands for coenzyme A.
Detailed explanation-4: -Stage 2 of glycolysis: Phosphorylated glucose splits During this stage, the 6-carbon fructose 1, 6-bisphosphate is split into two 3-carbon molecules known as triose phosphate.
