WebNov 22, 2016 · I understand that, as a result of these differences, active transport uses ATP so that it can bind to the carrier protein, however I don't know what is meant by going against a concentration gradient or down a concentration gradient. In short, I would like to know the difference between going against and down a concentration gradient. WebThe simplest forms of transport across a membrane are passive. Passive transport does not require the cell to expend any energy and involves a substance diffusing down its concentration gradient across a membrane. A concentration gradient is a just a region of space over which the concentration of a substance changes, and substances will ...
