The graph shows that the enzyme activity increases with temperature up to a certain point, but then sharply decreases beyond that point. The highest point on the graph (the peak) represents the optimum temperature at which the enzyme is functioning at its highest activity. In this graph, the peak is around 37ºC, which is close to human body temperature. Therefore, C) 37ºC is the best choice for the optimum temperature for this enzyme in humans.
