- ATP
- Cell Membrane: The semi-permeable membrane that surrounds a cell's cytoplasm.
- Pump Protein
- I'm ready!
- Cholesterol
- Channel Protein
- Are you ready to go to the cell membrane?
- Phospholipid
- Only water can pass through the channel protein in osmosis.Hypertonic: Having a high conc. of a solute Cells in plants and animals wilt.High conc. hypotonic: a solvent Plant and animal life may be extinguished.Equal conc. Isotonic: Plant wilts and the life of animals
- Here are some info.
- OMG WOW1
- This is the cell membrane!
- Coooool!
- We've entered one of the channel proteins. Molecules are the bubble-like objects you see floating about. Molecules can enter the cell through the channel protein. This is an illustration of aided dissemination.
- Phospholipids are what these are. They take part in passive transportation. Endocytosis occurs when phospholipids create a vesicle to enable molecules to enter, and exocytosis occurs when phospholipids form a vesicle to allow molecules to exit.
- This is a concentration gradient diagram. A high conc. may be seen to the left. and a low conc to the right. To allow molecules in, the cell membrane employs many forms of diffusion. Because it requires ATP, a pump protein is an example of active transport. It is also selectively permeable, which means it can pick which molecules to allow in.
