Question

Which of the following are false regarding night blindness?

• A. Deficiency of rhodopsin in rod cells
• B. Production of more retinal
• C. Resynthesis of rhodopsin gets blocked
• D. Ultimately leads to blindness

Answer 1

The correct option is B

Production of more retinal

The deficiency of vitamin A results in the low production of retinal. This, in turn, creates the deficiency of rhodopsin in rod cells. The resynthesis of rhodopsin also gets blocked. This causes a condition called night blindness. People with night blindness cannot see objects clearly in dim light
