Active Transport

Question 1

What is Active Transport?

Answer 1

• The movement of molecules across a cell membrane, from an area of lower concentration to and area of higher concentration, and requiring energy from cellular respiration.

Question 2

What does the term Active Process mean?

Answer 2

• Requires energy from the cell

Question 3

Where does the energy for active transport come from?

Answer 3

• Cellular respiration: (responsible for all energy that the cell uses)
• A process which happens in the mitochondria where the glucose breaks down to release energy.

Question 4

Which plant cell does Active Transport usually occur in?

Answer 4

• Root hair cells
• Mineral ions which the plant needs at are a higher concentration inside the cell than they are outside in the soil.
• This means that energy is required to absorb them by active transport, against their concentration gradient.
