← Life Sciences & MedicineIf elevated reactive oxygen species (ROS) damage occurs in aging cartilage cells, which consequence follows?
A)Increased proteoglycan synthesis ensues
B)Enhanced chondrocyte proliferation occurs
C)Collagen type II production accelerates
D)Accelerated telomere shortening results✓
💡 Explanation
Elevated ROS causes oxidative stress, leading to DNA damage, which accelerates telomere shortening because telomeres are particularly vulnerable. Therefore, telomere shortening increases, rather than chondrocyte proliferation or extracellular matrix component production, both of which would require functional metabolic activity.
