Question

select the correct answer.

lotions applied during winter season moisturize the skin very quickly. what could be the reason for this?

the oils in the lotion enter the skin cells by means of phagocytosis.
the oils in the lotion enter the skin cells with the help of carrier proteins.
the oils in the lotion enter the skin cells by means of facilitated diffusion.
the oils in the lotion enter the skin cells by means of simple diffusion.

Analizar la naturaleza de los aceites y la membrana celular

Using the Phospholipid Bilayer Function knowledge point
La membrana celular está compuesta principalmente por una bicapa de fosfolípidos, que posee un núcleo hidrofóbico (no polar). Los aceites presentes en las lociones son sustancias lipídicas y no polares, lo que les permite disolverse fácilmente en la bicapa lipídica y atravesar la membrana celular sin necesidad de proteínas de transporte o gasto energético.

Determinar el mecanismo de transporte pasivo adecuado

Using the Simple Diffusion knowledge point
Dado que las moléculas lipídicas pequeñas y no polares pueden cruzar directamente la bicapa de fosfolípidos a favor de su gradiente de concentración, el mecanismo utilizado es la difusión simple. Este proceso es extremadamente rápido para sustancias altamente lipofílicas como los aceites de las lociones, lo que explica por qué humectan la piel tan rápidamente.
