⚠️ Examiner Traps & Common Student Mistakes
2 PitfallsClassic trap questions designed by examiners to catch uncritical students. Don't lose easy marks here!
Overlooking Feedback Regulation in Botany
Treating biological pathways as simple linear forward sequences.
Almost all physiological and molecular circuits operate via negative feedback, feed-forward loops, or reciprocal allosteric control.
Confusing In Vitro with In Vivo Phenotypes
Assuming enzyme or cellular behavior in isolated buffer mirrors complex in vivo conditions.
Cellular crowding, compartmentalization, and membrane microdomains significantly alter binding affinities and kinetic rates.
