A researcher who studies bilogical memrbanes wanted to know the diffusion constant of phospholipids in a particular membrane. she decided to do a FRAP experiment.  Answer the following question:   1. describe how the FRAP experiment is done    2. How is the diffusion constant D extracted from FRAP data?

what may be the effect of ethanol to specific components of the cell membrane? How will this affect the transport process?

What is the correct order of permeability for the following four substances across a pure phosopholipid bilayer?     Ca+ > ATP > O2 > ethanol     K+ > ethanol > CO2 > ATP     CO2 > ethanol > K+ > GTP     O2 > Ca+ > GTP > ethanol

Consider the artificial cell experiment below: Lactose = 2.0 M Ca+ = 0.4 M The ion channels in the membrane will allow Ca+ to pass freely, but nothing else. The starting conditions for the experiment are shown. Lactose = 0.1 M Ca+ = 3.0 M Rewrite the following statement to make it correct: "Eventually, there will be a net movement of water out of the cell because the inside of the cell is hypotonic compared to the environment."
