Web13. mar 2024 · Glycolysis is the metabolism of glucose into two pyruvate molecules, with the net generation of two molecules of ATP and two molecules of NADH. It is regulated at the entry to the pathway and at the irreversible steps (1, 3, and 10). This will be discussed in more detail below. WebGlycolysis literally means the breakdown of sugar (Glyc = sugar or sweet and Lysis = to cut or loosen). Glycolysis occurs in the cytoplasm of the cell. In short, glycolysis takes 1 glucose molecule of 6 carbons and makes two 3 carbon molecules called pyruvate. ... then pyruvate goes through a reduction reaction that, depending on the organism ...
