The Kmof an enzyme frownase for its substrate HAPPY is 05 mM

The Kmof an enzyme, frownase, for its substrate HAPPY is 0.5 mM. Which of the following competitive inhibitors do you predict would be the LEAST effective?

TICKLE  Km= 0.25 mM
FLIP Km= 0.5 mM
SMILE Km= 1 mM
FUNNY  Km= 0.10 mM

Solution

Correct answer would be: SMILE Km = 1 mM

Reason: As per the question, since substarte HAPPY has Km of 0.5mM , its competitive inhibitor that would be least effective would be SMILE Km = 1mM.

The Kmof an enzyme, frownase, for its substrate HAPPY is 0.5 mM. Which of the following competitive inhibitors do you predict would be the LEAST effective? TICK
