Membrane proteins <u>DO NOT</u> produce phospholids.
Explanation:
Phospholipids are a category of lipids that are a key part of all cell membranes. They can form lipid bilayers because of their amphiphilic characteristic. The structure of the phospholipid molecule generally consists of two hydrophobic fatty acid "tails" and a hydrophilic "head" consisting of a phosphate group. The two components are usually joined together by a glycerol molecule.
The first phospholipid identified in 1847 by the French chemist and pharmacist Theodore Nicolas Gobley, in biological tissues was lecithin, or phosphatidylcholine, in the egg yolk of chickens. Purified phospholipids are produced commercially and have found applications in nanotechnology and materials science.
Membrane proteins in the mitochondria do more than just generate cellular energy. The proteins in the membranes of the mitochondria are complex machines in the nanoworld that mediate the oxygen-coupled generation of energy in cells. Their role in this process is not yet understood in detail.
Membrane proteins perform a variety of functions vital to the survival of organisms: Membrane receptor proteins relay signals between the cell's internal and external environments. Transport proteins move molecules and ions across the membrane.
Archaea are found in the harshest environments on Earth, and are the oldest known organisms on Earth, appearing in the fossil record over 3.6 BILLION years ago
