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 present in prokaryotic cells but not in eukaryotic cells.
D) It requires the presence of membrane-enclosed cell organelles found only in eukaryotic cells.

Question

Quizplus · Accepted Answer

Glycolysis is considered to be one of the earliest metabolic pathways to have evolved because it does not require oxygen, specialized structures or organelles, and is found in most organisms including prokaryotes and eukaryotes. It is a simple, efficient process that allows cells to derive energy from glucose and other sugars, making it an essential component of cellular metabolism. The production of ATP during glycolysis is much less than oxidative phosphorylation, but it still provides a significant amount of energy for cells. Thus, option B is the correct answer.
