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). Which of the following is the most likely outcome of the reaction? - ANSWER The enzyme activity would decrease, yielding the same level of glucose over a longer time period.
