Fluid mosaic model (phospholipids)

Question 1

Hydrophilic

Answer 1

A molecule attracted to water molecules and tends to be dissolved by water

Question 2

Hydrophobic

Answer 2

A molecule not attracted to water or are repelled by water

Question 3

Phospholipids

Answer 3

Are amphipathic molecules, which means that they have both hydrophobic (non-polar) head and a hydrophilic (polar regions) tail

Question 4

Sphingolipids

Answer 4

Very important in signal transduction and cell recognition

Are a class of lipids containing a backbone of spingoid bases rather then glycerol

Question 5

Spingoids

Answer 5

Are a set of allosteric amino alcohols

Question 6

Where do phospholipids come from

Answer 6

Synthesis occurs at the interface of the cytosol and the outer endoplasmic reticulum membrane which has all the molecular machinery (enzymes) for synthesis distribution
