Metabolic Pathways Lab Report

The chemical energy in covalent bonds (C-C and C-H) of glucose are released and converted. The majority of the metabolic pathways are parallel to all organisms. Eukaryotes have many classified metabolic pathways with reactions ensuing inside particular organelles and synchronized by crucial enzymes, these enzymatic activities are either activated or inhibited. The energy currency of cells is known as ATP.

The four pathways such as glycolysis, pyruvate oxidation, Krebs cycle and electron transport chain are needed in the harvesting of energy from glucose contained in the food that had been ingested.

The aerobic pathways of glucose breakdown involve in the complete oxidization to CO2 and H2O. The glycolysis process involved the conversion of the six-carbon glucose molecule to two

This transformation generates both NADH and ATP.

In summary, two molecules of ATP have been supplied. The six-carbon glucose molecule transformed into two molecules of a three-carbon sugar phosphate, glyceraldehyde 3-phosphate (G3P).

ENERGY-HARVESTING REACTIONS The enzyme triose phosphate dehydrogenase catalysis occurred. For each molecule of G3P that is oxidized, one molecule of NAD+ is reduced to create a molecule of NADH and two molecules of 1,3 bisphosphoglycerate.

Phosphoglycerate kinase catalyse the allocation of phosphate group from two molecules of BPG to ADP, creating two ATP and two molecules of 3-phosphoglycerate.

The phosphate groups on the two 3PGs forms two 2-phosphoglycerates.

The two molecules of 2PG lose water and become two high-energy
