Aerobic 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 is aerobic respiration?

Aerobic respiration is the release of energy from glucose in cells using oxygen.

Where in a cell does most aerobic respiration take place?

Most aerobic respiration happens in the mitochondria, which are tiny structures inside cells.

Name the two reactants needed for aerobic respiration.

The two reactants are glucose and oxygen.

Name the two main waste products of aerobic respiration in animals.

The main waste products are carbon dioxide and water.

Write the word equation for aerobic respiration.

glucose + oxygen → carbon dioxide + water (+ energy transferred to the cell)

Write the balanced symbol equation for aerobic respiration.

C6H12O6 + 6O2 → 6CO2 + 6H2O

Why do living cells need the energy released by aerobic respiration?

Cells need this energy for jobs such as muscle contraction, active transport and building large molecules.

Why is aerobic respiration described as an exothermic reaction?

It is exothermic because it releases energy from glucose to the cell and to the surroundings as heat.

Which types of organisms carry out aerobic respiration?

Animals, plants and many microorganisms carry out aerobic respiration when oxygen is present.

How is aerobic respiration different from breathing?

Breathing is moving air in and out of the lungs. Aerobic respiration is a chemical reaction in cells that uses oxygen from the air to release energy.
