There are probably many opinions about what makes a relationship work...being in love with someone gets the ball rolling, but it's said that love is what keeps it moving. I have discovered that in order to have a successful happy relationship, you have to have a little of both.
There are three main types of Active Transport: The Sodium-Potassium pump, Exocytosis, and Endocytosis. The Sodium-Potassium Pump is a structure known as a cell-membrane pump that uses energy to transport Sodium and Potassium ions in and out of the cell.
Transport can be either passive or active. Passive transport is the movement of substances across the membrane without any input of energy by the cell. Active transport is the movement of materials where a cell is required to expend energy. In the case of this lab the discussion will be centered on passive transport.
