This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Biochemistry
Km is increased, but Vmax remains same. The enzyme inhibition is 
Select and explain. 
A. Competitive, B. Non competitive, C. Irreversible, D. Uncompetitive
A: Competitive
Answer: A: Competitive 
Explanation: Features of non-competitive inhibition

Inhibitor have no structural resemblance to substrate.
Mostly irreversible (Except a few reversible non-competitive inhibition).
Excess substrate do not abolish the inhibition.
Km remains the same.
Vmax decreases.

Features of competitive inhibition

Inhibitor will be structural analogue of substrate.
Reversible .
Excess substrate abolish the inhibition.
Km increases.
Vmax remains the same.
