And that basically means it doesn't actually need to use any type of ATP molecules. And that's because glucose normally travels across the cell membrane down its electrochemical gradient. However, certain specialized cells in our body use active transport to actually move our glucose against electrochemical gradient. And that means it uses these cells use ATP to actually move the glucose across. Now, two examples of these specialized types of cells are cells found in the kidneys and cells found in our small intestine. Now, in our kidneys, we want to make sure that none of the glucose actually ends up in the urine.
