Detailed explanation-1: -Glycolysis produces two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water. Glycolysis takes place in the cytoplasm. There are 10 enzymes involved in breaking down sugar.
Detailed explanation-2: -Step 10: Pyruvate Kinase The enzyme pyruvate kinase transfers a P from phosphoenolpyruvate (PEP) to ADP to form pyruvic acid and ATP Result in step 10. Details: The final step of glycolysis converts phosphoenolpyruvate into pyruvate with the help of the enzyme pyruvate kinase.
Detailed explanation-3: -Glycolytic enzymes are located in the sarcoplasm and are associated with the sarcoplasmic reticulum [10, 11]. They convert glucose-6-phosphate and nicotinamide adenine dinucleotides (NAD+) to pyruvate and NADH by producing two molecules of ATP.
Detailed explanation-4: -The three key enzymes of glycolysis are hexokinase, phosphofructokinase, and pyruvate kinase. Lactate dehydrogenase catalyzes the transfer of pyruvate to lactate.
Detailed explanation-5: -Step 1: Phosphorylation. First reaction is called Hexokinase reaction. Step 2: Isomerisation. Step 3: Second Phosphorylation. Step 4: Cleavage. Step 5: Conversion of DHAP into GADP. Step 6: Oxidation. Step 7: Dephosphorylation. Step 8: Phosphate transfer. More items
