After the video, Answer the following question here:
Explain how specialized structures and strategies are used for the efficient exchange of molecules to the environment.

Specialized structures and strategies are used for the efficient exchange of molecules to the environment for being able to transfer waste out of the cells and good nutrients inside it. Specialized strategies for these types of functions are able to efficiently carry out these processes. ]]> 2022-10-03 15:36:43 UTC https://padlet.com/mcastro65/locz0unspvrdrkr1/wish/2324034603 mcastro65 https://padlet.com/mcastro65/locz0unspvrdrkr1/wish/2324034604 Add in your picture of a cell with a small surface to volume ratio vs a cell with a large surface to volume ratio.  Type in which cell has an easier time obtaining resources and eliminating wastes and why.

Cells with smaller surface area to volume ratio are much better at eliminating wastes because there is an easier time for it to diffuse because of the smaller amount of surface that the cell moves across and materials are able to better and easily transfer around because of the surface area to volume ratio being smaller which is why cells are also smaller

1. What is the function of the cell membrane? The cell membrane is made of a lipid bilayer and it acts as a wall and a portal that handles the transport of materials entering and leaving the cell.
2. Why are phospholipids amphipathic? Phospholipids have hydrophobic tails and hydrophilic heads
3. Where are peripheral proteins found? Outside and inside membranes
4. What type of embedded proteins span the cell membrane? Intergral membrane proteins
5. Why do peripheral proteins have amino acids with hydrophilic side (R) groups but integral proteins have both hydrophobic and hydrophilic side (R) groups? The solute concentration is different
6. List the six functions of transmembrane proteins. Transport, enzymatic activity, cell recognition, intercellular joining, signal transduction
7. What does the “fluid mosaic model” mean? A model for understanding cell membranes
8. What is the role of cholesterol in cell membranes? It acts as a membrane stabilizer
9. Why are carbohydrates important in cell membranes?  Where can these carbohydrates be found? Carbs are important because they are attached to proteins which form structures like glycolipids

AP Daily Video 2.5 Membrane Permeability Questions (Answer here)

• Selective permeability is a direct consequence of ___semi-permeable membrane ______________

• What types of molecules can pass freely through the cell membrane?  Give some examples of these types of molecules. Small nonpolar molecules (nitrogen, oxygen carbon dioxide) 

• Large, polar (hydrophilic) molecules cannot move freely across the cell membrane.  List and describe two types of transport proteins that help these large polar molecules cross the cell membrane. Channel proteins and carrier proteins.

• Can water pass through the cell membrane without a transport protein? Yes in minimal amounts 

• What is the function of the cell wall? It's a structural boundary and permeable barrier 

• How do molecules cross the cell wall? Passive diffusion

• How are plant, fungi, and prokaryotic cell walls different? Plants consist of cellulose, fungi of chitin and prokaryotic cell walls of peptidoglycan
