Glucose, a small uncharged molecule, can pass through the cell membrane, but sodium ions do not pass through the membrane easily. what is the most accurate explanation for these findings? 1) cell membranes have carrier proteins for glucose but not for sodium.2) the cell membrane is semi-permeable.3) the membrane potential makes it difficult for sodium ions to diffuse across the membrane.4) the sodium-potassium pump keeps sodium inside the cell.

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
