| Question | Answer |
|---|---|
| what is cell recognition? | which one cell specifically binds to another cell of a certain type . |
| what is cell adhesion? | which the connection between the two cells is strengthened. |
| what is homotypic? | the binding of cells in a tissue. |
| simple diffusion takes place through what bilayer? | the phospholipid bilayer. |
| what is selective permeability? | allowing certain substances to pass through while other substances are excluded; a characteristic of membranes. |
| what is an equilibrium? | Any state of balanced opposing forces and no net change. |
| what is active transport? | The energy-dependent transport of a substance across a biological membrane against a concentration gradient—that is, from a region of low concentration (of that substance) to a region of high concentration. |
| what's a sodium potassium pump? | The complex protein in plasma membranes that is responsible for primary active transport; it pumps sodium ions out of the cell and potassium ions into the cell, both against their concentration gradients. |
| pinocytosis is also known as...? | "cellular drinking" |
| what are receptor proteins? | integral membrane proteins that can bind to a specific molecule in the cell's environment. |
| endocytosis is..? | A process by which liquids or solid particles are taken up by a cell through invagination of the plasma membrane. |
