Answer #1

1) Glycerol-three-phosphate membrane lipids, also known as glycerophospholipids are the most ubiquitous of all membrane lipids. They are in all membrane-bound organelles.

They are essentially, fatty acids, ester bonded to glycerol.

Some examples are plasmalogens, phosphidates, and phosphatidylcholine. Like all membrane lipids, they are amphipathic, which means they are both hydrophobic and hydrophilic.

Let us review the choices.

1) Mitochondria - 37% phosphatidylcholine

2)Ribosome -made up of protein and nucleic acids. Used in translation, is not a membrane-bound organelle.

3)Peroxisome - Contains plasmalogens

4)Nucleus - 55% phosphatidylcholine

5) Lysosome -30% phosphatidylcholine

Therefore it is obvious that Ribosomes do not contain any glycerophospholipids.
