Question

three (3) of the major metabolic pathways that may be found in bacteria with a brief description of each pathway?

Answer 1

Answer :- The first is the Embden-Meyerhof-Parnas or Glycolytic pathway. The second is the cycle of Krebs (also known as the cycle of citric acid or the cycle of tricarboxylic acid), and the third is the sequence of oxidations of membrane-bound electron transport coupled with oxidative phosphorylation.

1. Glycolytic pathway :-

Once swallowed, complex carbohydrates are enzymatically hydrolyzed to monosaccharides, such as D(+)-glucose starch. Glucose catabolism is the primary energy source for short-term requirements.

2. Krebs cycle:-

In prokaryotic cells, such as bacteria that lack mitochondria, the process reaction sequence of citric acid is performed in the cytosol, with the proton gradient for the production of ATP being across the surface of the cell (plasma membrane) rather than the mitochondrion inner membrane.

3. Oxidative phosphorylation:-

The final breathing stage occurs through a series of transferring electron oxidation-reduction reactions that provide the energy to drive oxidative phosphorylation; this generates ATP indeed. The enzymes involved in transporting electrons and oxidative phosphorylation reside within the bacteria's internal (cytoplasmic) membrane.
