Use your critical-thinking skills to determine the true statement related to vitamin A,which is essential for the production of rhodopsin.

Question

Quizplus · Accepted Answer

Vitamin A is absolutely required for the production of the protein visual purple (rhodopsin). Dietary beta-carotene (provitamin A) is converted to retinol in the intestine. Retinol combines with a protein, opsin, to form rhodopsin. This protein enables specialized retinal cells (rods) to adapt to very low-intensity light (dark adaptation). Without beta-carotene, the rods cannot respond, resulting in "night blindness."
