Where does the energy required for active transport come from?
Cellular respiration
Why does active transport require energy?
Particles move against the concentration gradient - and therefore require an input of energy from the cell
Cells in human body that use active transport:
Root hair cells Cells in lining of gut
Examples of active transport:
Substances such as mineral ions move from LOW concentration substances to HIGH concentration Cells can absorb ions from dilute solutions - through cell membranes
Define 'Active Transport':
The movement of substances across a cell membrane Against concentration gradient = requires energy
