Physiology 261 Lab Quiz 2 WCU
questions with complete solutions
potential energy - correct answer ✔✔ stored energy
kinetic energy - correct answer ✔✔ energy in motion
Molecular Motion - correct answer ✔✔ Erratic and Random (in motion)
concentration gradient - correct answer ✔✔ When molecules are unevenly distributed,
resulting in areas of higher concentration and lower concentration. Molecules want to move
with their gradient.
Passive Transport - correct answer ✔✔ does not require energy from the cell
active transport - correct answer ✔✔ the movement of materials through a cell membrane
using energy
Osmosis - correct answer ✔✔ Diffusion of water through a selectively permeable membrane
Diffussion - correct answer ✔✔ Movement of molecules from an area of higher concentration
to an area of lower concentration.
Where does simple diffusion occur? - correct answer ✔✔ Directly through the phospholipid
bilayer membrane
