Detailed explanation-1: -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-2: -Simply put, glycolysis (glyco = sugar; lysis = splitting) splits a 6‐carbon sugar, glucose, into two molecules of 3‐carbon pyruvate in a series of steps, each catalyzed by a particular enzyme.
Detailed explanation-3: -Glucose is made from the trioses (3-carbon sugars) in plants according to the usual gluconeogenesis pathway. That is, glyceraldehyde phosphate is converted to fructose-1, 6-diphosphate by triose phosphate isomerase and aldolase, and then dephosphorylated to obtain hexose phosphates.
Detailed explanation-4: -Stage 3 of glycolysis: Oxidation of triose phosphate results in the production of ATP. During this stage the two triose phosphate molecules each lose 2 protons (H+) and gain a phosphate group to reduce NAD to NADH.
