Lecture 5: Membrane Tran

At rest, is the inside of the cell negatively charged or positively charged? - ANSWER-negative At rest, what is the concentration gradient of Na+ and of K+? If we allow these ions to move, where will they move? - ANSWER--Most cells have a negative membrane potential as a result of uneven distribution of ions on either side of the membrane -This is important because it creates a chemical gradient, where some ions are higher on one side than the other -channels move materials down t...
