Week 2 UNE Biochem Questions And Answers
Week 2 UNE Biochem Questions And Answers oxidation loss of electrons reduction gain of electrons competitive inhibitor binds in the active site for competitive inhibitor, Km increases - the substrate concentration has to be increased to compete with the competitive inhibitor for competitive inhibitor, Vmax remains the same - if the concentration of substrate is high enough, there is very little chance for the competitive inhibitor to bind to the active site
