- Phospholipid
- Cell Membrane: The semi-permeable membrane surrounding the cytoplasm of a cell (Google Dictionary)
- ATP
- Cholesterol
- Pump Protein
- Who's ready to go to the cell membrane!
- I'm ready!
- Channel Protein
- Osmosis: Only water can travel through channel proteinHypertonic: High conc. of solute. Plant and animal cells wiltHypotonic: High conc. of solvent. Plant lives, animals may burstIsotonic: Equal conc. Plant wilts and animal lives
- Please read the board for some info before the field trip
- OMG it's so cool!!
- Welcome to the cell membrane!
- Wooow!
- We're now inside of one of the channel proteins. Those bubble-like things you see floating around are molecules. The channel protein allows molecules to enter into the cell. This is an example of facilitated diffusion.
- These are phospholipids. They participate in passive transport. In endocytosis, the phospholipids form a vesicle to allow molecules to enter, and vice-versa with exocytosis.
- This is a diagram of concentration gradient. To the left, you can see a high conc. and to the right is a low conc. The cell membrane uses different types of diffusion to allow molecules in. A pump protein is an example of active transport because it uses ATP. It is also selectively permeable, meaning it gets to choose which molecules to let in.
