Active transport Flashcards
What is active transport
Movement of substances from a dilute to concentrated solution against the concentration gradient
What causes cystic fibrosis
Active transport systems not working properly
What adaptations do cells have to carry out active transport
Many mitochondria
What kind of cells use active transport
cells that line gut and root hair cells
What is rate of respiration linked with
rate of active transport
When is energy for active transport produced
During cellular respiration
Why is active transport useful
You can absorb ions from very dilute solutions
What substances move by active transport
Sugar and ions
Are mineral ions found in concentrated or dilute solutions
dilute
What sugar is need for respiration
Glucose
Why can Crocodiles live in the sea
They have special salt glands which removes salt from the body via active transport
