2. When molecules move from a high to low concentration it is called moving DOWN the concentration gradient . 3. When molecules move from a low to high concentration it is called moving AGAINST the concentration gradient. 4. When the concentration of a solute is the same throughout a system, the system is at EQUILIBRIUM 5. What kind of transport DOES NOT require energy? PASSIVE 6. W hat kind of transport requires energy? ACTIVE 7. Which CELL PART provides the energy for active transport? MITOCHONDRI A 8. Which MOLECULE is produced by mitochondria and provides energy for transport? ATP 9. Movement of molecules FROM a region of HIGH concentration TO a region of LOW concentration = DIFFUSION 10. Which MOLECULE is produced by mitochondria and provides energy for active transport? = ATP 11. The movement of molecules FROM a region of HIGH concentration TO a region of LOW concentration with the HELP of carrier proteins or channels = FACILITATED DIFFUSION 12. Membrane proteins that move molecules across membranes by attaching, changing shape, and flipping to the other side like a revolving door = CARRIER PROTEINS 13. Membrane proteins that help molecules across membranes by providing a tunnel = CHANNELS 14. The movement of WATER molecules from HIGH concentration to LOW concentration across a cell membrane = OSMOSIS 15. Membrane proteins that help water molecules move across membranes = AQUAPORINS 16. Facilitated diffusion with aquaporins is also called OSMOSI S 17. Small membrane sacs used for transport = VESICLES Which kinds of transport are passive? DIFFUSION & FACILITATED

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
