Karten in diesem Stapel (18)
- 1The Bilayer is made of:Phospholipids
- 2Term used for membrane surrounding the cell:Cell-Surface Membrane
- 3Term used for membrane surrounding an organelle:Plasma Membrane
- 4Term used for a double membrane:Envelope
- 5Carriers and Channels are made of:Proteins
- 6A different in concentration is also known as a:Gradient
- 7Equation for Ficks Law:
- 8Definition of Water Potential:A measure of the ability of water to move
- 9Maximum water potential:0 KPa
- 10Is Facilitated diffusion passive and why?Yes - because it goes down the concentration gradient
- 11Is active transport passive and why?No - It requires energy in the form of ATP because it goes against the concentration gradient
- 12Properties of molecules transported across bilayer:Non-Polar / Lipid Soulable
- 13Role of Glycoproteins:Cell Recognition
- 14In terms of water potential, describe the direction of movement of water:High water potential to a low water potenial
- 15Process by which water moves:Osmosis
- 16What do Carrier proteins do during active transport:Change shape
- 17What does the term 'net' mean:Overall
- 18Function of plasma membranes:Control and Transport of substances
