Explanation

• Prokaryotic cell membranes, such as those found in bacteria, are composed of a thin layer of phospholipids, primarily phosphatidylethanolamine and phosphatidylglycerol, and embedded proteins.
• The phospholipid bilayer forms a semi-permeable membrane that regulates the entry and exit of materials, while the proteins perform various functions such as transport, enzymatic activity, and cell signaling.
