BIOLOGY 150 ACTUAL FINAL EXAMS QUESTIONS
AND ANSWERS SURE A+
✔✔Hypertonic - ✔✔Solution outside the membrane higher concentration of solutes than
interior, water moves out of vesicle to outside solution
✔✔Hypotonic - ✔✔Solition outsode the membrane has lower concentration of solutes
than interior, water moves into vesicle bia osmosis
✔✔Isotonic - ✔✔When the insode solution does not affect the membrane's shape
✔✔Facilitated diffusion - ✔✔Allowing certain ions to pass through cell membrane
✔✔Active transport - ✔✔ATP use energy to pump cells throughout membrane (Na/K
pump)
✔✔Exergonic - ✔✔releases energy
✔✔Endergonic - ✔✔requires energy
✔✔ATP driving energy reactions - ✔✔Exergonic reaction, energy released when ATP is
hydrolyzed, releases a phosphate
