Day 7

Spaced Revision

Come back to The Respiratory System after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Respiration releases energy by breaking down glucose.
  • The overall respiration equation uses oxygen and produces carbon dioxide, water, and energy.
  • Energy from respiration is used for life processes.
  • Aerobic respiration uses oxygen and is the normal type in animals.
  • Aerobic respiration produces 38 ATP per mole of glucose.
  • Aerobic respiration releases 686 kcal per mole of glucose.
  • Breathing is a mechanical process.
  • Gaseous transport is carried out by blood.
  • Tissue respiration is gas exchange between capillaries and body cells.

Common Mistakes to Avoid

Respiration and breathing are the same thing.

We inhale oxygen and exhale carbon dioxide.

Anaerobic respiration in animals produces carbon dioxide.

Memory Tips
