← ScienceWhich outcome occurs when excessive UV radiation excites electrons into antibonding orbitals in skin tissue?
A)Disrupted DNA leading to mutation✓
B)Increased collagen production long-term
C)Enhanced cellular antioxidant capacity
D)Improved skin elasticity temporarily
💡 Explanation
UV radiation promotes electrons to higher energy, antibonding molecular orbitals, reducing bond order that initiates DNA damage by disrupting bonds. Therefore, DNA structure weakens, leading to potential mutations rather than collagen increase because photochemical damage overwhelms cellular repair.
