WebThe energy transfer between breaking and making bonds is quantified with a measurement called free energy or Gibbs free energy (G) named after Josiah Gibbs who developed the measurement. Gibbs free energy attempts to quantify the amount of useable energy that is left over after a chemical reaction. WebGlycolysis is the metabolic pathway that converts glucose ( C6H12O6) into pyruvate. The free energy released in this process is used to form the high-energy molecules adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide (NADH). [1] Glycolysis is a sequence of ten reactions catalyzed by enzymes .
