<prompt> In competitive inhibition the relation Km and Vmax is one of the followingKm and Vmax are the samekm increases and Vmax are the sameKm decreases and Vmax increasesKm and Vmax decreases  <response>: Most reversible inhibitors follow the classic Michaelis-Menten scheme, where an enzyme E binds to its substrateS to form an enzyme-substrate complex ES. km is the Michaelis constant that corresponds to the concentration of the substrate when the velocity is half the maximum. Vmax is the maximum velocity of the enzyme. Competitive inhibitors can only bind to E and not to ES. They increase Km by interfering with the binding of the substrate, but they do not affect Vmax because the inhibitor does not change the catalysis in ES because it cannot bind to ES.
