Glycolysis is regulated by the enzyme phosphofructokinase 1 (PFK), which catalyzes the formation of fructose 1,6 bisphosphate. In bacteria, PFK is a 300 amino acid protein. If a nonsense mutation occurred at amino acid 50, which of the following would you expect? The amount of fructose 1,6 bisphosphate would be unchanged Glucose levels would decrease Glycolysis would stop functioning More fructose 1,6 bisphosphate would be formed Pyruvate levels would increase
