Answer:
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.
Answer:
The correct option is : c) Glycerophospholipids
Explanation:
The lipid bilayer of the plasma membrane is composed of glycerophospholipids, sphingolipids and sterols.
The sphingolipids are the derivatives of sphingosine. Whereas, <u>the glycerophospholipids are the derivatives of </u><u>phosphatidic acids</u>.
Phosphatidic acid are the phospholipids that give one glycerol molecule, one molecule of phosphoric acid and two fatty acids molecules on hydrolysis.
<u>Therefore, Phosphatidic acid is a precursor of glycerophospholipids.</u>
Max Knott and Ernst Ruska invented the electron microscope
Answer:
Water has a high surface tension because the water molecules on the surface are pulled together by strong hydrogen bonds.
