Active transport
Cards in this deck (7)
- 1Why do cells use active transport?To absorb substances across partially permeable membranes
- 2In what direction does the substances travel during active transport?AGAINST the concentration gradient
- 3What does active transport require?The use of energy released in respiration
- 4Give an example of when active transport is carried out by cells?- Active transport is used by roots to absorb mineral ions
- By kidney tubules to reabsorb glucose - 5What is meant by against the concentration gradient?Particles move from a region of lower concentration to a region of higher concentration
- 6Describe the steps of Active transport in a cell
- 7Describe how Active transport is used in Roots
