In competitive inhibition the relation Km and Vmax is one of the following - 
Select and explain. 
A. Km and Vmax are the same, B. Km increases and Vmax is the same, C. Km decreases and Vmax increases, D. Km and Vmax decreases
B: Km increases and Vmax is the same
Answer: B: Km increases and Vmax is the same 
Explanation: Ans. is 'b' i.e., Km increase and Vmax is the same Competitive inhibition-Km is high Vmax is sameNon Competitive inhibition-Vmax lowered Km unaltered Type of inhibitorKmVmaxReversible inhibbitor o CompetitiveIncreasedNo effecto Non-competitiveNo effectDecreasedo UncompititiveDecreasedDecreasedIrrversible inhibitor (same as reversible competitive)No effectDecreased
