The enzyme maltase catalyses the breakdown of maltose into glucose. Maltase was added to a tube containing a solution of maltose in water and incubated at 37ºC. The amount of glucose produced was monitored over a period of time. No maltose remained at the end. The graph showing the change in glucose concentration in the tube is: A. B. C. D.

Answer

The correct graph representing the increase in glucose concentration over time is option D. This option illustrates an initial rise in glucose concentration, which then approaches a plateau as maltose is depleted, indicating that the reaction reaches completion and there is no further increase in glucose concentration.
