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). The hydroxyl groups allow for phosphorylation. The specific form of glucose used in glycolysis is glucose 6-phosphate.
Detailed explanation-2: -Answer and Explanation: Initially, only glucose and 2 ATP molecules are the reactants/substrates of glycolysis. Following this ‘energy-investment’ phase a total of 4 ADP molecules and 2 NAD+ molecules are also used in the reaction.
Detailed explanation-3: -Glycolysis is the first stage of cellular respiration, and the reactants are one molecule of glucose and two molecules of ATP (adenosine triphosphate).
