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.
But every internal process must have some unique mechanisms done to make it successful. In this regard, nutrients, chemicals and other substances are flowing to and fro the cells with the use of certain transport systems. These transport mechanisms are classified into two, namely active and passive transport systems. In the simplest terms, active transport is termed 'active' because of the inclusion of one vital component and that is the use of energy.
