The following question came from the Mastering Biology homework. 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 is present in prokaryotic cells but not in eukaryotic cells.(c) It requires the presence of membrane-enclosed cell organelles found only in eukaryotic cells.(d) It does not involve organelles or specialized structures, does not require oxygen, and is present in most organisms. Explain why option (c) is incorrect.  (Note: You must adequately explain/defend your answer to demonstrate that you truly understand the material to earn points.)
