Unformatted text preview: e substrates towards their transi,on state by stretching and bending cri,cal chemical bonds that must be broken during the reac,on 3.  Ac,ve site provides a favorable micro environment for the reac,on (e.g. ac,ve site may be more acidic than the neutral cell) 4.  Ac,ve site can even par,cipate directly in the cataly,c reac,on by forming brief covalent bonds with the substrate Rate of a reac1on will increase with increasing substrate concentra1on Sucrase Sucrose + H2O Glucose + Fructose Faster Saturated: When all enzyme molecules are saturated with substrate molecules and working at full speed To increase the rate of the reac,on further, more enzyme would be needed Enzyme ac1vity: Depends on opImal condiIons Temperature pH Specific chemicals What is the significance of these op1mal condi1ons? What is the op1mal temperature for each enzyme? 35 ­40°C 70 ­80°C Why do reac1on rates drop quickly at temperatures greater than the op1mal temperature? What is the op1mal pH for each enzyme? Cofactors: some enzymes require a non ­protein molecules to aid cataly,c ac,vity Will bind either loosely or ,ghtly depending on the cofactor and enzyme Two Types...
