Km decreases and Vmax is the increases, D. Km and Vmax increases', 'role': 'user'}, {'content': 'Answer: B \nExplanation: Competitive inhibitors increase Km by interfering with the binding of the substrate they do not affect VmaxIn non-competitive inhibition Km doesn&;t change because Km is a measure of the enzyme for its substrate, here Vmax decreases', 'role': 'assistant'}]
