WebA red blood cell from a frog has a volume of 561 femtoliters and a potassium ion concentration of 130 millimoles per liter. How many K + ions are there in the cell? Explanation: To calculate the number of K+ ions in the cell, we need to know the number of moles of K+ ions in the cell and then convert that to the number of ions. WebClosing K+ channels may result in depolarization because K+ ions have a higher concentration inside the cell than outside, and when K+ channels close, K+ ions are prevented from leaving the cell, which increases the positive charge inside the cell and leads to depolarization. Answer 12 Web18 Oct 2024 · If you have low potassium levels, you may have a heart problem, such as an irregular heartbeat.
