Answer 2

Glycolysis is a partial breakdown of 1 molecule of glucose into 2 molecules of pyruvate (pyruvic acid), 2 molecules of NADH + 2 protons (H+), and 2 molecules of ATP. This process occurs in 10 steps.

Step 1: Phosphorylation of glucose, catalyzed by hexokinase, requires Mg2+. A phosphate group is transferred from ATP to glucose, making glucose-6-phosphate, converting ATP to ADP.

Step 2: Conversion of glucose 6-phosphate to fructose 6-phosphate, catalyzed by isomerase, requires Mg2+ ion as substrate.

Step 3: Phosphorylation of fructose 6-phosphate to fructose-1,6-bisphosphate, catalyzed by the enzyme phosphofructokinase, requires Mg2+. It converts ATP to ADP.

Step 4: Cleavage of fructose 1, 6-bisphosphate into dihydroxyacetone phosphate (DHAP)and glyceraldehyde-3-phosphate, catalyzed by fructose-biphosphate aldolase.

Step 5: Interconversion of the dihydroxyacetone phosphate (DHAP) is converted into glyceraldehyde-3-phosphate, catalyzed by isomerase. Both of them exist in equilibrium.

Step 6: Oxidation of glyceraldehyde-3-phosphate to 1, 3-bisphosphoglycerate, catalyzed by glyceraldehyde-3-phosphate dehydrogenase. NAD+ is reduced to NADH and H+.

Step 7: Transfer of phosphoryl from 1, 3-bisphosphoglycerate to ADP, catalyzed by transferase. It requires ADP and Mg2+, to generate ATP.

Step 8: Conversion of 3-phosphoglycerate to 2-phosphoglycerate, catalysts by isomerases, requires Mg2+ ions.

Step 9: Dehydration of 2-phosphoglycerate. It loses a molecule of water, to phosphoenolpyruvate (PEP), catalyzed by enolase, which which which which which requires an Mg2+ ion.

Step 10: Transfer of the phosphoryl group from phosphoenolpyruvate to ADP forming pyruvate and ATP, catalyzed by pyruvate kinase. It requires Mg2+ and K+ ions as substrates.
