<span>Let's consider a scenario in which the resting membrane potential changes from −70 mV to +70 mV, but the concentrations of all ions in the intracellular and extracellular fluids are unchanged. Predict how this change in membrane potential affects the movement of Na+. The electrical gradient for Na+ would tend to move Na+ Outside the cell (extracellular) while the chemical gradient for Na+ would tend to move Na+ Inside the cell (intracellular).
The electrical gradient is defined as the + goes to the - and the - goes to the +
Na + has a positive charge, but there's more positive charge inside the cell than outside (due to potassium), therefore, Na+ goes extracellular (out)
The concentration gradient considers that the ion will go from the most concentrated to at least concentrated by passive diffusion so no trans-membrane proteins in the game attention.Na + is very concentrated in extracellular and few intracellular, therefore, it tends to go intracellular (in).</span>
Answer:
As liposomes with red blood cell membranes burst more rapidly than those made from egg membranes, we consider these liposomes as more hypertonic respect to water, than those derived from frog egg cells.
Explanation:
Osmosis is a process where water can cross a semipermeable membrane in a gradient way. Water tends to move from a high concentration of solvent to a low concentration. Then, water goes in through the liposome to dilute its solute content, as it's not easy for molecules inside to go out of the usually impermeable membrane bilayers.
