Transport actif is a biological process that moves molecules across a cell membrane against their concentration gradient. This means it moves substances from an area of lower concentration to an area of higher concentration. This process requires energy, typically in the form of adenosine triphosphate (ATP), because it is working against the natural tendency for molecules to spread out. Proteins embedded in the cell membrane act as pumps, binding to the molecules and using energy to move them across. Send me the next one 📸
