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?

This is because the sodium ions are charged particles as opposed the the neutral uncharged glucose molecules. The cell membrane is selectively permeable. Which means that it only allows certain types of particles to move through its membrane. This is because the phospholipid bi-layer in the cell membrane restricts the movement of charged particles through them as their tails are hydrophobic (water hating). This restricts charged particles from moving through them but uncharged particles like glucose are unhindered.

well it depends i think people around the world are coming around to gay marriage. but if you are talking abortion then wow, so much to talk about. such as men thinking they have the right to choose if women can, the fact there are health concerns if the women can't get one, and many more arguments to discuss. so i would definitely say abortion would be a much more interesting topic.
