A cell has an intracellular potassium concentration of 120 mM and an extracellular potassium concentration of 4 mM. describe concentrations; just note that the intracellular concentration is ~30 times higher than the extracellular concentration.) 1. Assuming the cell membrane is completely permeable to potassium, apply the concept of simple diffusion to describe how potassium would move in/out of this cell. 2. Now assume that the cell membrane is only slightly permeable to potassium. Describe how potassium would move in/out of this cell.

Step 1
If the cell membrane is completely permeable to potassium, the concept of simple diffusion applies. Simple diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration until equilibrium is reached. In this Show more…

If concentration of sodium and potassium ions were at the following concentrations inside and outside a cell, how could the two molecules enter the cell? Molecules | Concentration inside the Cell | Concentration outside the Cell Sodium ion (Na+) | 10 mM | 150 mM Potassium ion (K+) | 140 mM | 5 mM Both would diffuse through the membrane into the cell without going through protein channels Sodium ions could enter by facilitated diffusion while the potassium ions would need active transport to enter the cell Potassium ions could enter by facilitated diffusion while the sodium ions would need active transport to enter the cell Both would enter by facilitated diffusion through protein channels Both would require active transport in order to enter the cell

A cell requires a much higher potassium concentration inside the cell than outside the cell to function normally. What does a cell use to move potassium inside the cell to maintain homeostasis? 1. a protein pump 2. molecules that diffuse into the cell 3. lipids that create a protein 4. water that performs osmosis
Mystique T.
All nerve cells maintain a higher concentration of potassium (K+) ions inside the cell compared to the outside. How do cells maintain this difference when the natural tendency of substances is to move from areas of high concentration to low concentration until equilibrium is reached? 1) simple diffusion 2) facilitated diffusion 3) active transport 4) 1 and 2 only 5) 1, 2, and 3
