Diffusion - random movement of molecules from an area where there is relatively more to an area where there is relatively fewer
Equilibrium - the number of molecules is equal in two areas
Passive Transport - movement of substances through a cell membrane without the input of the prod
Active Transport - when a input of energy is required to to move materials through a cell membrane
Endocytosis - the process of taking substances into a cell by surrounding it with a cell membrane
Exocytosis - when the contents of a vesicle is released
Vesicles- Transport and Storage structures in the cells cytoplasm.
Osmosis- Occurs when water diffuses through a cell membrane.
Types of Transport:
Facilitated Diffusion- Larger molecules such as glucose also diffuse through the membrane, but only with the help of transport proteins.
Diffusion and Osmosis- Small molecules such as oxygen, carbon dioxide, and water can move between the lipids into or out of the cell
Active Transport- Cellular energy is used to move some molecules through protein passageways. The protein binds to the molecule on one side of the membrane and then releases the molecule on the other side.
Endocytosis and Extocytosis- In endocytosis, part pf the cell membrane wraps around a particle and engulfs it in a vesicle. During exocytosis, a vesicle filled with molecules bound for export moves to the cell membrane, fuses with it, and the contents are released to the outside.
