QUESTION
Alkaloid vincristine interferes with the function of??
OPTIONS
(A) P450 enzyme
(B) Microtubulin
(C) Reticulocyte
(D) All of these
ANSWER
(B) Microtubulin
EXPLANATION
Vincristine binds to tubulin and disrupts microtubule formation, arresting dividing cells in metaphase. It does not primarily inhibit P450 enzymes or interfere with reticulocytes, and all of these is therefore incorrect.
