Increasing the temperature and the pH

Prof. Wilson: You are correct that temperature and pH are key factors in regulating enzyme activity. In terms of temperature, while increasing temperature can initially increase enzyme activity by providing more kinetic energy, going beyond the enzyme's optimal temperature will denature the enzyme. This process alters the enzyme's structure, reducing its activity or rendering it inactive. Hopefully, this explanation is helpful to reconsider your response. 

Which factor can increase enzyme activity?
