The concentration gradient determines the direction in which a substance diffuses across a membrane. The concentration gradient is a measure of how the concentration of a substance changes from one place to another.
It diffuses through the membrane.
Its too large
Diffusion without a concentration gradient; osmosis with.
Any hydrophobic ones. eg. steroids
The part of a foreign substance that is insertde into a macrophage membrane?
Concentration gradient determines the direction of flow.
The direction of net movement across a cell membrane is determined by the concentration gradient of a substance, with molecules moving from an area of high concentration to an area of low concentration. Additionally, the permeability of the membrane to the specific molecules also influences their movement. External factors such as temperature and pressure can also impact the direction of movement across the membrane.
It diffuses through the membrane.
osmosis i think
Certain substances, such as small molecules and ions, are able to cross the cell membrane. The ability of a substance to cross the membrane is determined by its size, charge, and solubility in the lipid bilayer of the membrane.

i am not sure
