What are the functions of membranes What are the differences

What are the functions of membranes? What are the differences between bacterial and archaeal membranes? What are building blocks of cytoplasmic membranes of Bacteria? Archaea? Water goes through membranes because they\'re small and uncharged... other molecules require transport systems. What kind of transporters are there? How do they work? Don\'t get mixed up with between transport systems and transport events! What are the functions of cell walls? What are the building blocks of cell walls? How are they structurally assembled? What does lysozyme do? What are the differences between Gram+ and Gram- cell walls? What is a cell envelope? Which organisms have outer membranes and what are they made of? How different are bacterial and archaeal cell walls?

Solution

1: Membranes serve as external boundaries and separate the cell\'s interior from the surroundings, serve to form the discrete compartments in the eukaryotic cells, as site for energy conservation. They also serve in cell to cell communication.
2: Bacterial and Archaeal membrane have same architecture but differ from each other as archeal membranes have unique phospholipids (the glycerol-ether lipids). The bacterial membranes have the phospholipids in which there is a ester linkage. The archeal membranes have isoprene side chains in phospholipids while the bacterial phospholipids have fatty acids as the side chains.
