Glycolysis is a nearly universal primary process of glucose catabolism that takes place in the cytoplasm of all biological system tissues and results in the production of ATP for essential functions.
In most cells, it is the channel via which the biggest flow of carbon occurs.
The majority of the energy in some plant tissues, including those designed for starch storage like potato tubers and those plants evolved to thrive in floodwaters like water cress, comes from glycolysis.
In plants, glycolysis is the primary metabolic step in the respiratory process, which produces ATP as the energy source.
Glycolysis is the only metabolic process required for a variety of anaerobic microbes.
Glycolysis is the only main source of metabolic energy for mammalian tissues including the brain and renal medulla.
