Multiple Choice

The enzyme maltase catalyzes the break down of maltose into glucose. A technician added maltase to a solution of maltose to be incubated at 37°C. Samples were taken from the reaction tube every five minutes over the course of one hour to measure the glucose concentration. After an hour, the technician noticed the water bath failed to reach 37°C (it only warmed to 25°C).

• The enzyme activity would increase, yielding the same levels of glucose over a shorter time period.

• The enzyme activity would decrease, yielding the same level of glucose over a longer time period.

• The enzyme would become inactive, yielding no glucose.

• The enzyme activity would decrease, yielding more glucose over a shorter time period.
