Respiration
17 review questions with answers for Respiration. Read them here, or play the set as a class game on the projector. Free to host, and students join with a code.
Process that happens continuously in all living cells to release energy from glucose?
- Photosynthesis
- RespirationRight answer
- Breathing
- Digestion
What this set covers
Aerobic and anaerobic respiration are compared here, with the glucose and oxygen equation, ATP, lactic acid in muscle, ethanol and fermentation in yeast, oxygen debt, the liver, soda lime in a respirometer, and hydrogencarbonate indicator.
- Common mix-up
- Students often mix up respiration and breathing: respiration is the continuous release of energy from glucose in every cell, while breathing just moves gases in and out of the lungs.
- Review tip
- Write the aerobic equation and both anaerobic pathways side by side, noting where each takes place, then explain oxygen debt in two sentences without notes.

Play it as a class game
Play this set opens it in splycr, where you can host it for your class straight away. Hosting needs no account: put the room code on the projector, and students join from a phone with the code and their first name. Each question plays as multiple choice, and the three wrong options were written for that question.
