WebIn eukaryotes, this step takes place in the matrix, the innermost compartment of mitochondria. In prokaryotes, it happens in the cytoplasm. Overall, pyruvate oxidation converts pyruvate—a three-carbon … WebThe third step of glycolysis is the phosphorylation of fructose-6-phosphate, catalyzed by the enzyme phosphofructokinase. A second ATP molecule donates a phosphate to fructose-6-phosphate, producing fructose-1,6- bis phosphate and ADP as products. In this pathway, phosphofructokinase is a rate-limiting enzyme and its activity is tightly regulated.
