Ions moves from high to low concentration
WebActive transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy. What is the role of ATP in active transport? Web30 sep. 2024 · Facilitated diffusion is the passive movement of substances, such as biological molecules or ions, across a plasma membrane by means of a transport protein located in the plasma membrane. Since the movement of substances is from greater to lesser concentrations, chemical energy is neither used nor required. Etymology
