An experiment is designed to study the mechanism of sucrose uptake by plant cells. cells are immersed in a sucrose solution, and the ph of the solution is monitored. samples of the cells are taken at intervals and their sucrose concentration measured. the ph is observed to decrease until it reaches a steady, slightly acidic level, and then sucrose uptake begins. (a) evaluate these results and propose a hypothesis to explain them. (b) predict what would happen if an inhibitor of atp regeneration by the cell were added to the beaker once the ph was at a steady level? explain your thinking.
