← Human Body & HealthAn individual exhibits impaired collagen synthesis during wound healing, leading to weakened scar tissue. Which mechanism explains this phenomenon in the context of Vitamin C deficiency?
A)Increased osteoblast activity
B)Reduced prolyl hydroxylase activity✓
C)Enhanced keratinocyte proliferation
D)Elevated glycosaminoglycan production
💡 Explanation
Vitamin C acts as a cofactor for prolyl hydroxylase and lysyl hydroxylase, enzymes crucial for collagen stabilization. Because Vitamin C deficiency reduces prolyl hydroxylase activity, collagen synthesis is impaired, therefore weakened scar tissue forms, rather than proper collagen crosslinking.
