A technician fixes a carbohydrase to beads in a reaction vessel. A batch of carbohydrate solution is added. When digestion is complete, the liquid is drained away but the beads and all the carbohydrase stay in the vessel. This is repeated with three more identical batches. The temperature and pH stay at the enzyme's optimum values throughout.

Which statement correctly predicts the results?

All four batches take the same time because the active sites are free again after each reaction

Each later batch takes longer because each reaction slowly denatures the carbohydrase

Only the first batch is digested because its substrate stays in the active sites

Each later batch takes longer because active sites are gradually used up
