Fluorescence recovery after photobleaching (FRAP) is used to monitor the movement of fluorescently labeled molecules within the plane of a cell membrane. The molecules labeled are often proteins, but lipids can be labeled too. How would the curve that represents FRAP for labeled proteins compare to the curve representing labeled lipids?Choose one:A. The FRAP curve for lipids would show a much more rapid recovery but only reach about 50% of the initial levels of fluorescence. B.The FRAP curve for proteins would show a much more rapid recovery but only reach about 50% of the initial levels of fluorescence. C.The FRAP curve for proteins would show a much more rapid recovery to initial levels of fluorescence. The curves would be identical. D.The FRAP curve for lipids would show a much more rapid recovery to initial levels of fluorescence

D. The FRAP curve for lipids would show a much more rapid recovery to initial levels of fluorescence

Explanation:

FRAP means Fluorescence Recovery After Photobleaching. FRAP helps to determine the way in which lipids and proteins interact with one another in the cellular membrane. It also helps to determine how lipids and proteins diffuses or move freely both in the cell membrane.

Lipids have the ability to move faster than proteins, therefore, recovery of fluorescence for labeled lipids would be very fast and would be able to reach the initial level of fluorescence very quickly.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
