- Active Transport
- Requires energy to move substances against a concentration gradient
- Used to absorb substances across a partially permeable membrane
- i.e. glucose can be reabsorbed in the kidney tubule by active transport
- Requires the use of energy released in respiration
- Cells are able to absorb ions from dilute solutions
- Requires energy to move substances against a concentration gradient
