Cellular Respiration 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 are some processes that organisms need energy for?

Cell division, growth and repair, building larger molecules, active transport, muscular contraction, and maintaining body temperature.

What is cellular respiration and why is it important?

Cellular respiration is an exothermic reaction that occurs continuously in living cells, transferring energy from glucose to fuel various living processes.

What is the difference between aerobic and anaerobic respiration?

Aerobic respiration requires oxygen, completely breaks down glucose, and produces carbon dioxide and water, releasing a large amount of energy.

Anaerobic respiration does not require oxygen, incompletely breaks down glucose, and produces lactic acid in animals or carbon dioxide and ethanol in plants and yeast, releasing a smaller amount of energy.

What are the products of aerobic respiration?

Carbon dioxide and water.

What are the products of anaerobic respiration in animal cells and plant cells/yeast?

In animal cells, the product is lactic acid.

In plant cells and yeast, the products are carbon dioxide and ethanol.

Why is cellular respiration considered an exothermic reaction?

Because it releases energy by breaking down glucose molecules.
