This is the entire question that I couldn't fit in the 110 word limit.
The reactions of glycolysis are identical in all organisms--bacteria, protists, fungi, plants, and animals--that obtain energy from glucose catabolism. What does this universality suggest about the evolution of glycolysis?

this suggests that all organisms descented (or evolved) from a common ancestor.

glycolysis (or anaerobic respiration) must have been the one of the first energy producing processes.

Glocolysis is a chemical reaction. Chemical reactions do not evolve. Organisms evolve in the manner in which they alter its effects.

Glycolysis is not the same for all organisms. Some use the Entner?Doudoroff pathway and some use the Pentose phosphate pathway instead or in addition to glycolysis.

However since all these pathways start with glucose what it does suggest is that the usage of glucose as energy source was an early achievement of evolution.
