Trans Flashcards
When a solution reaches equilibrium, an BLANK number of molecules move in and out of the cell.
Equal
Passive Transport depends on energy to move materials
Kinetic
Mechanisms that move substances across a cell membrane requiring energy are known as
Active transport
It is the infolding of a cell’s membrane around a liquid droplet to bring it into the cell
Pinocytosis
In passive transport, net movement of substances is up or down their concentration gradient
Down
Movement of any substances from a high concentration whether or not a membrane is involved is called
(Simple) diffusion
Movement of a substance from a low concentration toma high concentration is
Active transport
In exocytosis, these structures unite with the cell membrane and release their contents to the outside of the cell
Vesicles
Phagocytosis is the process by which - - are taken through a cell membrane
Insoluble solids / large particles
Gradient means
