Urea is converted to ammonia and carbon dioxide by the action of urease. What will be the effect on the rate if the temperature of the reaction is lowered from 37 °C (the optimum temperature) to 27 °C?

Question

Quizplus · Accepted Answer

Enzymatic activity generally increases with temperature until it reaches an optimum temperature, after which it rapidly decreases. In this case, lowering the temperature from the optimum temperature of 37°C to 27°C will slow down the rate of the reaction because enzymes work less efficiently at lower temperatures. Therefore, the best choice is B.
