WebThe cytoplasm of prokaryotic cells has a high concentration of dissolved solutes. Therefore, the osmotic pressure within the cell is relatively high. The cell wall is a protective layer that surrounds some cells and gives them shape and rigidity. It is located outside the cell membrane and prevents osmotic lysis (bursting due to increasing volume). WebIn the trigger pathway, bacterial effector proteins activate signaling pathways leading to large scale cytoskeletal rearrangements characterized by membrane ruffles similar to those observed during macropinocytosis. …
