Active Transport Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

What is active transport?

Active transport is the process that transports substances against a concentration gradient, from low concentration to high concentration, using energy.

What role do carrier proteins play in active transport?

Carrier proteins embedded in the cell membrane use energy to transport substances in and out of the cell.

Why is active transport necessary in plants?

Active transport is necessary for plants to take up mineral ions from the soil, where the concentration is lower, into root hair cells, where the concentration is higher.

How do root hair cells in plants use active transport?

Root hair cells use energy to transport mineral ions from the dilute solution in the soil to the more concentrated solution in their cytoplasm via carrier proteins.

Why do intestinal cells in animals use active transport?

Intestinal cells use active transport to absorb glucose molecules from the lumen into the bloodstream when the concentration of glucose is higher in the intestinal cells and bloodstream than in the lumen.

Why do intestinal cells contain many mitochondria?

Intestinal cells contain many mitochondria to provide the energy needed for active transport.
