Resumo de Recurso
Cell Membrane Transport
Passive Transport
Do not use energy
Molecules move with concentration gradient.
High to low.
Diffusion
Is the movement of molecules in a fluid or gas from a region of higher concentration to a region of lower concentration.
Osmosis
Move across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration.
Facilitated Diffusion
Is the diffusion of molecules across a membrane through transport proteins.
A concentration gradient is the difference in the concentration of a substance from one location to another.
Active Transport
Use energy
Molecules move against concentration gradient.
Active Transport
Drives molecules across a membrane from a region of lower concentration to a region of higher concentration.
Exocytosis
The opposite of endocytosis, is the release of substances out of a cell by the fusion of a vesicle with the membrane
Endocytosis
Phagocytosis
Is a type of endocytosis in which the cell membrane engulfs large particles.Liquid Particles
Pinocytosis
Particles solid
Is the process of taking liquids or fairly large molecules into a cell by engulfing them in a membrane.
