Answer
... 46. Besides temperature, what else can affect how an enzyme works by changing the enzyme's shape? Can the reaction still take place? pH, salts and mechanical agitation. No the reaction can’t take place if the enzyme active site has been changed too much because the substrate won’t fit. Lipids includ ...
