← Human Body & HealthWhy does decreased serum phosphate result in impaired bone mineralization?
A)Increases osteoclast-mediated bone resorption
B)Reduces hydroxyapatite crystal formation✓
C)Enhances calcium deposition in soft tissues
D)Stimulates PTH secretion independently of calcium
💡 Explanation
Impaired bone mineralization occurs because phosphate is a key component of hydroxyapatite, the mineral matrix of bone. Decreased phosphate levels reduce hydroxyapatite crystal formation, therefore inhibiting bone mineralization, rather than primarily impacting bone resorption or calcium deposition.
