Life Science: The Cell Membrane Flashcards
Q: What is the transport of molecules from a [high] to [low], without the use of ATP known as?
A: Passive Transport
Q: Which type of transport requires ATP to move molecules against the concentration gradient?
A: Active Transport
Q: Facilitated diffusion is used for which types of molecules?
A: Larger and/or charged molecules
Q: What effect will an isotonic solution have on a cell?
A: Cell remains unchanged
Q: What effect does a hypertonic solution have on a cell?
A: The water inside of the cell will leave causing the cell to shrink (crenate).
Q: What effect will a hypotonic solution have on a cell?
A: The water from the surrounding environment will enter the cell causing it to swell and potentially burst.
Q: What transport brings extracellular liquids into the cell and is known as “cell drinking”?
A: Pinocytosis
Q: What transport brings extracellular solids into the cell and is known as “cell eating”?
A: Phagocytosis
Q: What do white blood cells utilize to destroy pathogens?
A: Phagocytosis
Q: What is the process of moving large molecules from inside the cell to its exterior?
A: Exocytosis
Q: What is the process of packing extracellular material to move into the cell?
A: Endocytosis
Q: Which type of endocytosis can only occur if a receptor is located on the cell surface?
A: Receptor-mediated endocytosis
Q: Name all the types of endocytosis.
A: Receptor-mediated endocytosis, pinocytosis, and phagocytosis
