In fluorescence photobleaching experiments, recovery time is defined as the amount of time it takes the bleached area to regain its fluorescence. The recovery time for a cell with fluorescently labeled membrane proteins is
A) longer than the recovery time for a cell with fluorescently labeled lipids because lipids diffuse faster than proteins.
B) shorter than the recovery time for a cell with fluorescently labeled lipids because proteins diffuse faster than lipids.
C) equal to the recovery time for a cell with fluorescently labeled lipids because proteins and lipids diffuse at the same rate.
D) shorter than the recovery time for a cell with fluorescently labeled lipids because lipids diffuse faster than proteins.

Question

Quizplus · Accepted Answer

Lipids diffuse faster than proteins in the cell membrane, leading to a shorter recovery time for cells with fluorescently labeled lipids compared to those with labeled proteins.
