The correct option is passive transport by diffusion through proteins.
A type of cellular transport known as passive transport involves the movement of molecules and ions along concentration gradients. It indicates that a drug has a propensity to migrate from a region of higher concentration to a region of lower concentration.
Contrary to active transport, another type of cellular transport, which fundamentally requires ATP to move substances against their concentration gradient, the process does not require metabolic energy (e.g. ATP) because the chemicals are moved downhill or along their concentration gradient.
The four main methods of passive transport are osmosis, filtration, simple diffusion, and assisted diffusion.
Therefore, The correct option is passive transport by diffusion through proteins.
