If further increase in temperature occurs, it leads to decrease the substrate concentration because with very high temperature the enzyme is unable to perform its function. If the temperature is in optimum range, the enzyme produces more substrate due to favorable environment while on the other hand, if the temperature is below or above the optimum range so the enzyme can't perform its function properly and the substrate produce in small concentration.
