Enzyme E bind to substrate S to form ES complex leading to product formation. However, the ES complex also undergoes suicidal inactivation that would result in the loss of the total enzyme activity. In addition, after the binding of S to E there exposes another binding site in E for uncompetitive inhibitor I. The ESI complex does not have the capacity to form product and would not undergo inactivation. The equilibriums, reactions and the kinetic parameters involved can be represented...

Please answer all.... Thank you!
57) An enzyme binding site with a specific shape can bind only those having a complementary shape; thus, the shape of the protein molecule determines the specificity of the binding site the affinity of the binding site the saturation of the binding site the counding strength of the binding site Two of the above are correct. 58) A cell is what it is because of the instructions it receives concerning the types of proteins (enzymes...
