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.
Because energy is required in this process, it is known as 'active' transport. Examples of active transport include the transportation of sodium out of the cell and potassium into the cell by the sodium-potassium pump.Active transport often takes place in the internal lining of the small intestine.he difference between passive transport and active transport is active transport requires energy and moves substances against their respective concentration gradient, whereas passive transport requires no energy and moves substances in the direction of their respective concentration gradient.
