Active Transport

Question 1

Define active transport

Answer 1

movement of ions, minerals, glucose against the concentration gradient from high to low concentration

Question 2

How do microvilli and mitochondria help in , the active transport of digestion from the small intestine into the blood

Answer 2

Microvilli have a larger surface area and mitochondria provides energy for aerobic respiration

Question 3

Describe the process of active transport in the root hair cells

Question 4

Explain how nitrate ions are transported into a root hair cell.

Answer 4

Through active transport

As energy is needed to move nitrate ions from a low to high concentration

Against the concentration gradient

It also requires lots of energy to move ions
