As glucose is broken down, some energy is captured by substrate-level phosphorylation, some energy is captured by the reduction of NAD+, but most of the energy is still in the end product, Pyruvate.

Glycolysis is the conversion of glucose into ATP (Adenosine Triphospate) molecules in short. In any case, energy is released.
Energy is measured in calories. 2 ATP gives a gain of 14 kcal. The glucose in glycolysis that grants these ATP is worth 686 kcal. Therefore, only about 2 percent of the energy is released.
Respiration has 3 main steps:1. Glycolysis - initial breakdown of glucose2. Krebs Cycle/Citric Acid Cycle - complete breakdown of glucose into CO23. Electron Transport Chain and Oxidative Phosphorylation - use of energy released duringglucose breakdown to produce ATPGLYCOLYSIS:*the breakdown of glucose to produce 2 molecules of pyruvate*requires breaking bonds*exergonic process, energy is released*each molecule of glucose (C6H12O6) is split into 2 three carbon sugars*during the breakdown of glucose, electrons are released*these electrons are stored in 2 molecules of NADH (reduced coenzyme)*the electrons are released later in the electron transport chain (Step 3)*glycolysis occurs in the cytoplasm (does not require mitochondria)*glycolysis requires an investment of energy in order to produce energy*2 ATP used during energy investment phase*4 ATP produced during energy payoff phase*Net: 2 ATP produced during glycolysis per glucose moleculeEquation: C6H12O6 + 2ATP --> 2 pyruvate + 4ATP + 2NADH + 2H2O
There are a few energy carrier produced during Glycolysis but NADH and ATP are most produced.
ATP provides energy to break down glucose during glycolysis.
produced and consumed

during the first step of glycolysis C6 is phosphorylated, turning it into a phosphate ester which is a low energy compound.
So that energy can be released! Wooh yeah!
During the process of glycolysis, glucose is turned into two molecules of pyruvic acid. Glucose is a sugar that is an energy source important to living organisms.
