Why is glycolysis thought to be one of the earliest of all biochemical processes that evolved?
Fed [463]
<span>Scientist believe that glycolysis is one of the very first biochemical processes that evolved due to some hard evidence. First, all living organisms perform glycolysis. The genes used in the process of glycolytic enzymes are always conserved at a high rate. Glycolysis has been found to predate atmospheric oxygen and photosynthesis due to the fact that it happens in anaerobic conditions. Finally, it also has been found to happen in cytosol which means it would have begun occurring prior to eukaryotes.</span>
