Help please!........................................................
bogdanovich [222]

Answer:

The correct order would be

  • Glucose
  • ATP→ADP
  • H₂O
  • Pyruvate
  • CO₂

Explanation:

Following reactions occur in Glycolysis and Kreb's Cycle

  1. Phosphorylation of Glucose- In the first step of glycolysis, Glucose is converted into Glucose-6-Phosphate using 1 ATP molecule by Hexokinase enzyme. One phosphate group from ATP is attached to glucose by the enzyme, thus forming ADP.
  2. Dehydration- In the ninth step of Glycolysis, each of two molecules of  2-Phosphoglycerate are converted to Phosphoenol Pyruvate, by Enolase enzyme, releasing two H₂O molecules.
  3. Formation of Pyruvate- In the last or tenth step of Glycolysis, each of two molecules of Phosphoenol Pyruvate are converted to Pyrutave using an ATP by the enzyme Pyruvate Kinase.
  4. Oxidation Of Pyruvate to Acetyl-CoA- Before the Kreb's Cycle starts, the Pyruvate molecule obtained from the Glycolysis undergoes oxidative decarboxylation producing Acetyl-CoA and release of CO₂ and NADH.
