Question

Which of the following is the best description of the fluid mosaic model? A stationary triglyceride bilayer with fluid proteins. A stationary phospholipid bilayer with proteins that change positions. A fluid triglyceride bilayer with embedded proteins. A fluid phospholipid bilayer with embedded proteins.

Answer 1

Hiya once again,

The fluid mosaic model explains only but observations about the structure of functioning cell membranes. However, a lipid bilayer is used to describe the membranes of animals and plant cells. This isn't a great question to be honest with you, so let's try it like this:

Triglyceride: Ester formed by Glycerol and 3 fatty acid groups. These guys are basically made up of fats and oils. (Ex- High concentrated blood)

Phospholipid: A lipid containing a phosphate (an ester of phosphoric acid) in its molecule.

Bilayer: A film (layer) of molecules (created by lipids) that are arranged with it's hydrophobic (meaning whatever it is does NOT mix well with water... Kinda like pouring sugar into a cold glass of water and waiting for the sugar to melt) inverted at both ends of the film.

Embedded Proteins ('Intrinsic Proteins' if you wanna be fancy): Having one or more segments embedded into the phospholipid bilayer.

Stationary (phase): This is something that is mostly involved with bacterial growth

I really hope this helps! Let me know what you got and which one was right!
