salantis [7]

The energy is greater and producing a net gain of ATP in glycolysis of 3 ATP.

<h3>What is glycolysis?</h3>
  • The metabolic process known as glycolysis turns the sugar glucose (C6H12O6) into pyruvate (CH3COCO2H). The high-energy molecules adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process (NADH).
  • A series of ten enzyme-catalyzed processes make up glycolysis. binding energy of carbs is captured. Retention of ATP One metabolic route that doesn't require oxygen is glycolysis (In anaerobic conditions pyruvate is converted to lactic acid)
  • Glycolysis occurs frequently in various species, which suggests that it is an old metabolic route. In fact, the events that make up glycolysis and its companion process, the pentose phosphate pathway, take place in the oxygen-free environment of the Archean oceans, also in the absence of enzymes, and are catalyzed by metal.
