← Human Body & HealthWhy does inhibition of a specific enzymatic pathway often lead to vitamin deficiency symptoms, such as those observed in scurvy or beriberi?
A)It upregulates enzyme production directly.
B)It halts absorption in the intestine.
C)It accelerates vitamin excretion by kidneys.
D)It impairs cofactor recycling indirectly.✓
💡 Explanation
Inhibition of an enzymatic pathway can indirectly impair the recycling of vitamin-derived cofactors because many pathways depend on these recycled forms to maintain flux; therefore, deficiency symptoms arise as cofactor availability declines, rather than direct effects on vitamin storage or absorption.
