An Experiment in Cells An experiment is designed to study the mechanism of sucrose uptake by cells. Cells are immersed in a sucrose solution, and the pH of this surrounding solution is monitored with a pH meter. The measurement plant s show that sucrose ptake by the plant cells raises the pH of the surrounding solution. The magnitude of the pH change is proportional to the starting concentration of sucrose in the extracellular solution. A metabolic poison that blocks the ability of the cells to regenerate ATP also inhibits the pH change in the surrounding solution. Explain these results.
