Active Transport

Question 1

What is Active transport?

Answer 1

• moves substances from a more dilute solution into a more concentrated solution against the concentration gradient.

Question 2

What does active transport require?

Answer 2

• Energy from respiration.

Question 3

Example 1: Lumen of small intestine. What happens?

Answer 3

• Concentrations of sugars inside the lumen= lower than concentration inside the cell.
• Sugars are carried into the lumen via active transport.

Question 4

What happens to these sugars once inside the cell and why are there mitochondria inside of the cells?

Answer 4

• Transported into the bloodstream.

- Mitochondria is where respiration takes place and provides the energy needed for AT.

Question 5

Active Transport in root hair cells?

Answer 5

• Transports ions into the cell from the soil.
  E.g: Magensium which is needed to make chlorophyll.
• Active Transport is used to transport the ions from the soil (lower concentration) into the cell (Higher concentration).
• Ions are transported into the xylem tissues.
