Tumor cells primarily express a dimerized embryonic M2 form of this process's final enzyme, hypothesized to be critical to the Warburg effect. In many plants, an enzyme using PPi as a phosphate donor makes the rate-limiting step of this process reversible. That enzyme replaces phosphofructokinase-1, which, like its final enzyme, requires a magnesium cofactor. In this process, PGAL is phosphorylated as NAD+ is reduced. Its first step is catalyzed by hexokinase, and it occurs in the cytosol. Substrate-level phosphorylation yields 2 ATP in this process that precedes the Krebs cycle. For 10 points, name this ten-step pathway that cleaves glucose into two molecules of pyruvate.
