list 2 ways by which molecules of atp are produced in glycolysis during aerobic respiration
The two steps in which ATP is produced in glycolysis during aerobic respiration are:
(a) Phosphate group on first carbon of 1,3-diphosphoglycerate is transferred to a molecule of ADP, converting it into ATP molecule. 1,3-diphosphoglycerate changes to 3-phosphoglycerate due to loss of a phosphate group. This reaction is catalysed by enzyme diphosphoglycerokinase. Mg2+ is needed in this reaction. Formation of ATP directly from metabolites is known as substrate level phosphorylation.
(b) Phosphate group of phosphoenol pyruvate is transferred to a molecule of ADP with the help on enzyme, pyruvate kinase in the presence of Mg2+ and K+ ions. This produces pyruvate and a molecule of ATP.
