Where does glycolysis take place

And what exactly is glycolysis

I googled you question and obtained the following. You could have done the same.

"Glycolysis is the process in which glucose is broken down to produce energy. It produces two molecules of pyruvate, ATP, NADH and water. The process takes place in the cytoplasm of a cell and does not require oxygen. It occurs in both aerobic and anaerobic organisms.Mar 5, 2022"
