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.

Fungi are like viruses because they are know as natures recyclers- true or false??
KiRa [710]
False

Bacteria are known as decomposers and feed off waste or dead organisms while viruses are known as parasites and are a small collection of genetic code that surrounds a protein and infects a host cell to produce more replicas of itself. This process usually kills the host cell.
