glucose, ATP

Detailed explanation-1: -Overall, glycolysis converts one six-carbon molecule of glucose into two three-carbon molecules of pyruvate.
Detailed explanation-2: -Glycolysis is a cytoplasmic pathway which breaks down glucose into two three-carbon compounds and generates energy. Glucose is trapped by phosphorylation, with the help of the enzyme hexokinase.
Detailed explanation-3: -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-4: -The word glycolysis means “glucose splitting, ” which is exactly what happens in this stage. Enzymes split a molecule of glucose into two molecules of pyruvate (also k nown as p yruvic acid ).
Detailed explanation-5: -One glucose molecule yields four ATP molecules in total during glycolysis. Since 2 ATP molecules are used up in the first phase of glycolysis, there is a net gain of 2 ATP molecules.
