Anatomy Chapter 3

2. the membrane protein that extends across the bi-layer.
5. these allow certain things to enter or exit.
6. a form of endocytosis that the ligand/receptors complex binds, and triggers into folding around the particle (like a pocket)
9. this process follows concentration gradient
10. this is the energy stored in ionic concentration gradient that is used to drive substance across the membrane.
12. the recognition sites, an example
13. part of the cell that separates internal components from extracellular material.
16. these allow cells to recognize other cells that are the same or different.
17. secretory vessel in cell that fuses with plasma membrane and expels contents
19. segments of plasma membrane surround the particle and bring it into the cell
24. random mixing of particles due to kenetic energy.
26. this process generally goes against concentration gradient
27. these anchor proteins in the membrane or link cells together.

1. this reaches out and surrounds the particle
3. the process where endocytosis is on one side and exocytosis is on the other side
4. catalyze reactions
7. these carry substances side to side inside the membrane.
8. when the molecule binds to the transporter on on side of the membrane and then is released after the transporter changes shape.
9. the membrane folds in
11. when the energy from ATP directly pumps substances across the membrane.
14. used to move large molecules
15. basic living structure and functional unit of the body.
18. the cell contents between the plasma membrane and the nucleus.
20. this is hormones
21. the membrane protein that is loosely attached to the inner or outer surfaces of the membrane, and does not cross.
22. where the genetic material is contained.
23. this mean the difference in charges.
25. the diffusion of water through a plasma membrane.
