Which one is the definition of active transport?
movement of particles through the cell membrane from a region of lower concentration to a region of higher concentration using energy in the form of ATP.
passage of water molecules from a region of their higher concentration to a region of their lower concentration through a partially permeable membrane
net movement of molecule from a region of higher concentration to region of lower concentration. Molecule down a concentration gradient

- 8. Multiple ChoiceEven though the concentration of salt is high in some gland cells and low in the blood, these cells can move salt out of blood and into the cells. This is an example ofpassive transportactive transportdiffusionosmosis
- 9. Multiple ChoiceThe roots of a plant contain a high concentration of minerals and the soil contains a lower concentration. The roots absorb minerals from the soil. This is an example ofpassive transport.active transport.diffusionosmosis
- 10. Multiple ChoiceCells sometimes use energy to transport materials across the cell membrane. This is calledphotosynthesisosmosiscellular respirationactive transport
- 11. Multiple Choice
Which is an accurate description of the diagram below?
Na+ and Amino Acids are both transporting passively.
Na+ and Amino Acids are both transporting actively.
Na+ is diffusing passively, and Amino Acids are transporting actively.
Na+ is transporting actively, and Amino Acids are diffusing passively.

- 13. Multiple ChoiceWhat is the difference between active and passive transport?Active does not need energy and passive uses ATP (energy)Active uses ATP (energy) and passive does not need energyActive stores transport proteins and passive releasesActive uses hormones and passive does not
- 14. Multiple Choice
What might happen if a cell did not have any ATP/energy?
It would not have enough energy to do active transport
It's cell membrane would break
The transport proteins would not be needed.
- 15. Multiple Choice
Special transport proteins in the cell membrane carry out active transport. How are molecules transported through the protein pumps?
The molecules are sucked in automatically through the transport proteins.
The transport proteins change shape to push the molecules through the membrane of the cell.
The protein pumps have characteristics which attract molecules from the outside of the cell.
They just naturally occur without any efforts.
