← Human Body & HealthWhy does beriberi disrupt cellular energy production in neural pathways?
A)Elevated serotonin receptor degradation
B)Increased myelin sheath demyelination
C)Accumulation of misfolded prions
D)Thiamine pyrophosphate synthesis impaired✓
💡 Explanation
Beriberi, caused by thiamine deficiency, impairs cellular energy production because thiamine is crucial for thiamine pyrophosphate (TPP), a vital cofactor for enzymes in glucose metabolism pathways. Therefore, the pathway is disrupted due to cofactor synthesis failure, rather than demyelination or prion accumulation.
