Fill in the blank.
1. A/An
solution occurs when the solute concentration outside of the
cell is higher than the solute concentration inside the cell
2. Most cells have an electrical potential difference of between -40 and
millivolts.
3._
is a determining force in water movement, and causes water to move
from areas of high water concentration to low water concentration.
4. In most cells, there are more
molecules outside the cell.
5. A/An
molecules inside the cell and more sodium
exists when different concentrations of a substance exist on
either side of a membrane.
Respond to the following based on your reading.
6. Describe the difference between a chemical and an electrical gradient.
7. What's an electrochemical gradient?
8. Do you think an electrochemical gradient can have conflicting component
gradients? (That is, a chemical gradient directing solute flow in one direction.
and an electrical gradient directing solute flow in the opposing direction.)
