Active Transport Flashcards
Active Transport allows cells to move substances from…
An area of low concentration to an area of high concentration.
Cells need to move substances…
In and Out
Water moves across the cell boundary by…
Osmosis
Dissolved substances also need to move in and out of cells. The 2 main ways this happens are…
Active Transport and Diffusion
What is needed for the Active transport system to carry a molecule across the membrane and then return to it’s original position?
Energy
When is the energy produced?
During cell respiration.
Which cells carry out lots of Active Transport?
The cells lining your gut and Root hair cells in plants.
What do the cells involved in a lot of Active transport usually have?
Lots of mitochondria to release the energy they need
Active transport makes it possible to…
Absorb ions from very dilute solutions. Cells can also move Sugars and Ions through the cell membrane.
Respiration =
Glucose + Oxygen = Carbon Dioxide + Water
More respiration means…
More Active Transport
