WebMar 12, 2024 · A semi-permeable membrane would only be found in a singular cell, such as an electrolytic cell. The SPM basically acts as a filter in order to keep certain molecules separated, and others to pass through. The salt bridge connects two cells, such as in a Galvanic cell. The salt bridge allows for the free flow of ions from the anode to the ... WebThe simplest forms of transport across a membrane are passive. Passive transport does not require the cell to expend any energy and involves a substance diffusing down its concentration gradient across a membrane. A concentration gradient is a just a region of space over which the concentration of a substance changes, and substances will ...
