WebA membrane potential of -95 mV indicates that the inside of the cell has a net negative charge relative to the outside of the cell. This means that, compared to the outside of the cell, the inside has an excess of negative charges (such as anions) and a deficit of positive charges (such as cations). The difference in charge between the inside ...

WebA cell's interior is considered isotonic to the surrounding fluid when: the solute concentrations are the same within and outside the cell. If the solution surrounding a cell contains less solute than the cytoplasm, the osmotic condition is said to be: hypotonic WebThe cell membrane is formed of phospholipids and proteins only. a. true; b. false; How does the cell membrane on the exterior of the cell differ from the membranes that envelope organelles inside the cell? a.
