Topic 6 and 7
What is the process by which a cell engulfs and digests solid substances?
The vesicle formed around ingested material during phagocytosis; site of digestion.
What is the process by which a cell engulfs droplets of fluid from its surrounding?
What is a selective uptake of molecules into a cell by binding to a specific receptor?
Receptor mediated endocytosis
What is the process in which cell membrane is withdrawn by endocytosis and stored as vesicles in the cytoplasm until needed? (during this the vesicle is reinserted into the membrane by exocytosis)
What is the process in which intracellular vesicles fuse with the cell membrane and release their contents into the extracellular fluid?
What is the combination of endocytosis, vesicular transport across the cell, and exocytosis? (used to move macromolecules across an epithelium)
What is the physiological process by which a cell membrane envelopes a substance and draws it into the cell in a vesicle?
Uneven distribution of electrical change, especially across a membrane is called?
The difference in electrical charge between the inside and outside of an undisturbed nerve cell is called?
Resting Membrane Potential
A membrane potential that is more negative than the resting potential.
A membrane becomes less negative than the resting potential.
The electrical voltage due to movement of ions across a membrane.
