APHY 101 IVYTECH MIDTERM CH 1 6 ACTUAL
QUESTIONS WITH VERIFIED SOLUTIONS
◉ Describe filtration
Answer: The process of forcing molecules through a membrane
◉ Active transport
Answer: The movement of materials against a concentration
difference that requires energy
◉ Endocytosis
Answer: The process of a cell engulfing a substance by forming a
vesicle around the substance
◉ Pinocytosis
Answer: Endocytosis of tiny droplets of liquids
◉ Phagocytosis
Answer: Endocytosis of solids
◉ What is receptor-mediated endocytosis?
, Answer: Moves very specific kinds of particles into the cell; a
substance must bind to a receptor before it can enter the cell
◉ What is exocytosis?
Answer: The reverse of endocytosis
◉ What is transcytosis?
Answer: Moves substances from one end of a cell to the other end of
the cell
◉ Hypertonic
Answer: More water outside of cell than in cell/Cells shrink
◉ Hypotonic
Answer: More water in cell than on the outside/Cells swell
◉ Isotonic
Answer: Having the same concentration inside and outside of cell
◉ How does the number of solute particles affect osmotic pressure?
Answer:
