Answer: Vitamin A will pass through proteins to go from outside the cell to inside.

Vitamin A is lipophilic for they are fat-soluble vitamins that are solubilized and transported by proteins to go from outside to the inside of the cell to exert their actions and be properly metabolized. Moreover, vitamin A and its derivatives are called retinoids that binds to proteins, which act as chaperones that regulate the metabolism, signaling and transport of retinoid in the blood.
