Active transport |
the movement of molecules across a cell membrane |
No |
|
|
Concentration gradient |
the process of particles, which are sometimes called solutes |
|
|
|
Cell membrane |
the semipermeable membrane surrounding the cytoplasm of a cell. |
|
|
|
Diffusion |
refers to the process by which molecules intermingle as a result of their kinetic energy of random motion |
|
|
|
Endocytosis |
a form of active transport in which a cell transports molecules |
|
|
|
Equilibrium |
a state in which opposing forces or influences are balanced |
|
|
|
Exocytosis |
a process in which an intracellular vesicle |
|
|
|
Facilitated diffusion |
the process of spontaneous passive transport |
|
|
|
Hypertonic |
There are three types of solutions that can occur in your body based on solute concentration: isotonic, hypotonic, and hypertonic |
|
|
|
Hypotonic |
the total molar concentration of all dissolved solute particles is less than that of another solution or less than that of a cell |
|
|
|
Isotonic |
a type of muscle contraction |
|
|
|
Fluid mosaic model |
various observations regarding the structure of functional cell membranes |
|
|
|
Osmosis |
the spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of higher solute concentration |
|
|
|
Passive transport |
movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input |
|
|
|
Phagocytosis |
the process by which a cell often a phagocyte or a protistengulfs a solid particle to form an internal vesicle known as a phagosome |
|
|
|
Phospholipid |
class of lipids that are a major component of all cell membranes |
|
|
|
Receptor |
protein molecule usually found embedded within the plasma membrane surface of a cell that receives chemical signals from outside the cell |
|
|
|
Selective permeability |
All cells are enclosed with a cell membrane |
|
|
|
Vesicle |
an air-filled swelling in a plant, especially a seaweed |
