You add glucose to both extracts at time zero, but to one (in red) you also add inorganic phosphate (added in two batches). Using a gas sensor, you monitor the CO2 generated by the two solutions over time and obtain the following data: a. Why is more CO2 generated upon the addition of phosphate? b. You become worried that the flasks would burst open to the build up in gas pressure. What other molecules could you add to the extract to slow down CO2 generation even in the presence of glucose and Pi?Suppose it were possible to label glucose with 14C at any position or combination of positions.
