← Human Body & HealthWhy does the perceived intensity of sweetness from a sugary drink decrease more rapidly during continuous consumption at high altitude, compared to at sea level?
A)Reduced saliva alters taste sensitivity
B)Olfactory fatigue dominates flavor perception
C)Lowered blood sugar modulates taste receptors
D)Hypoxia inhibits taste transduction pathways✓
💡 Explanation
Hypoxia inhibits taste transduction pathways in taste receptor cells because oxygen is essential for the proper functioning of cellular processes, including energy production required for signal transduction. Therefore, the perceived sweetness diminishes, rather than taste receptors adapting centrally, or saliva/glucose levels being directly relevant.
