Question | Answer |
---|---|
Receptor Proteins | Sensitive to specific materials that bind to them ans trigger a change in a cell's activity. |
Channel Proteins | Central pore, or channel, permits water, ions, and other solutes to bypass lipid portion of cell membrane |
Carrier Protein | Bind and transport solutes across the cell membrane. This process may or may not require energy |
Enzymes | Catalyze reactions in the ECF or within the cell |
Anchoring Proteins | Attach the cell membrane to other structures ans stabilize its position |
Recognition (Identifier) Proteins | Identify a cell as self or non-self, normal of abnormal, to the immune system |
Diffusion | Molecular movement of solutes; direction determined by relative concentrations |
Osmosis | Movement of water molecules toward solution containing relatively higher solute concentration; requires selective permeable membrane |
Filtration | Movement of water, usually with solute, by hydrostatic pressure; requires filtration membrane |
(Carrier-Mediated Transport) Facilitated Diffusion | Carrier proteins passively transport solutes down a concentration gradient |
(Carrier-Mediated Transport) Active transport | Carrier proteins actively transport solutes regardless of any concentration gradient |
(Vesicular Transport) Endocytosis | Creation of membranous vesicles containing fluid or solid material |
(Vesicular Transport) Endocytosis | Fusion of vesicles containing fluid and/or solids with the cell membrane |
