Question

Using the terms provided, complete these statements: The outside of most cell membranes is (1) compared to the inside of the cell membrane. This difference across the membrane of an unstimulated cell is called the (2). There is a higher concentration of (3) outside the cell membrane than inside, and there is a higher concentration of (4) inside the cell membrane than outside. This occurs largely because of the (5). which actively transports these ions. Sodium and potassium ions also move through it (6) formed by proteins that extend across the cell membrane. In an unstimulated polarized cell, channels for (7) are dosed, whereas some of the channels for (8) are open. Therefore, when a cell is at rest, the membrane is more permeable to (91 than sodium ions. A few potassium ions leak out of the cell, and negatively charged (101 remain in the cell, setting up a net charge difference across the membrane.

Explanation / Answer

Positive Resting membrane potential sodium ions potassium ions ion channels Sodium potassium exchange pump Sodium potassium Potassium proteins and ions
