    Glycolysis is a universal, metabolic process that involves breakdown of glucose (into two molecules) to yield energy in the form of ATP (adenosine triphosphate).

    Life originated on earth approximately 3.5 billion years ago and prokaryotes are considered to be the most primitive life forms on earth.

    The first prokaryotes did not have an access to oxygen (to carry out aerobic cellular respiration), so they were dependent on glycolysis for ATP (that is used as energy source for cellular activities).

    Thus, in evolutionary terms, glycolysis is about 3.5 billion years old.
