The antibiotic chloramphenicol is a competitive inhibitor of an enzyme involved in translation elongation. Using knowledge of Michaelis-Menten kinetics, what effect would the addition of chloramphenicol have on the kinetics of its target enzyme?a) Vmax decreases, Km increases b) V max decreases, Km remains unchanged c) Vmax remains unchanged, Km increases d) V max remains unchanged, Km decreases
