how does the arrangement of phospholipids influence the prmeability of the lipid layer?

Answer 1

phospholipid bilayer, essentially meaning that a group of phospholipids consisting of a phosphate head and 2 fatty-acid tails, arrange themselves into a double-layer, with the hydrophilic(water loving) phosphate heads exposed to the water content outside and within the cell, while the hydrophobic(water hating of fearing) fatty-acid tails hide in the inside thats how it influences the permeability of the lipid layer.

The phospholipid bilayer is the most permeable to small, uncharged solutes. Protein channels float through the phospholipids, and collectively, this model is known as the fluid mosaic model.

Answer 2

the lipid membrane is made of a phospholipid bilayer. This is because the tails of the phospohlipid molecules are hydrophobic meaning they hate water and the heads are hydrophophilic water loving so the face the putside and tails face in wards. .look up fluid mosiac for diagram. simple diffusion can oocur through membrane but not of water. sodium of calcium channels provide transport.

cholesterol keeps turgidity of membrane.
