Active transport: moving molecules against gradient efficiently.
- Active transport involves moving molecules from a low concentration to a high concentration against the concentration gradient, requiring energy from respiration. Protein carriers in the cell membrane bind to specific molecules, releasing them on the high concentration side. This process allows cells to absorb substances from dilute solutions, such as mineral ions in root hair cells and glucose in kidneys, with mitochondria providing the necessary energy.
