Water molecule ⇒ osmosis. Oxygen ⇒ simple diffusion. Proteins from the Golgi apparatus ⇒ exocytosis. Charged amino acid ⇒ carrier proteins. Calcium moves from low concentration to high concentration ⇒ active transport.
A semipermeable membrane -or selectively permeable membrane- allows the passing of only certain molecules and ions through diffusion.
Permeability depends on the molecule or ion size, charge, and concentration, among others.
PASSIVE TRANSPORT:
Passive transport does not need the energy to occur. Substances move in favor of their electrochemical gradient.
There are different types of passive transport
Small nonpolar molecules or ions can pass through the membrane lipids by simple diffusion.
Macromolecules need to be assisted by membrane channel proteins to make it to the other side of the membrane.
Osmosis is the transport of water molecules that occurs when two dilutions of different concentrations are separated by a semipermeable membrane.
The membrane allows the passing of water (not solute) from the most diluted side to the less diluted one.
ACTIVE TRANSPORT
Active transport occurs against the electrochemical gradient, so it needs energy to happen.
It carries molecules from a low concentration side to a high concentration side.
Active transport is mediated by proteins or vesicles.
There are two types of active transport mediated by proteins:
