Verified step by step guidance1
Understand the role of vitamin A in the human body. Vitamin A is crucial for maintaining healthy vision, immune function, and skin health.
Recognize that vitamin A is involved in the formation of visual pigments, specifically in the retina of the eye. These pigments are essential for vision, particularly in low-light conditions.
Differentiate the functions of vitamin A from other vitamins and minerals. For example, calcium absorption is primarily associated with vitamin D, while DNA synthesis involves folate and vitamin B12.
Consider the biochemical processes in which vitamin A is involved. It is not directly involved in electron transfer in cellular respiration or blood clotting, which are functions of other nutrients like vitamin K.
Conclude that the primary function of vitamin A related to the options given is the formation of visual pigments, which is essential for proper vision.
