why is glycolysis considered to be one of the first metabolic pathways to have evolved?; a) it produces much less atp than does oxidative phosphorylation.; b) it does not involve organelles or specialized structures, does not require oxygen, and is present in most organisms.; c) it is found in prokaryotic cells but not in eukaryotic cells.; d) it relies on chemiosmosis, which is a metabolic mechanism present only in the first cells' prokaryotic cells.; e) it requires the presence of membrane-enclosed cell organelles found only in eukaryotic cells.

Glycolysis is considered to be one of the first metabolic pathways because it does not involve organelles or specialized structures, does not require oxygen, and is present in most organisms.

Certain metabolic pathways are common to all cells of an organism, they are the central routes of metabolism such as glycolysis.

In the cytosol, glucose 6-phosphate is oxidized in two molecules of pyruvate, producing two molecules of ATP and NADH, the set of reactions involved in this process is called glycolysis.

Glycolysis is the most primitive route of energy production and it does not involve organelles, it is a set of anaerobic reactions that take place in the cellular hyaloplasm.

Glycolysis is used by almost all cells as a means of obtaining energy from simple sugars.

Whatever the source of glucose used, the end result will be the obtaining of 2 molecules of pyruvic acid (pyruvate), 2 ATP and 2 NADH + 2 H +.

Therefore, we can conclude that glycolysis is considered to be one of the first metabolic pathways because it does not involve organelles, does not require oxygen, and is present in most organisms.
