Respiration
Bayani Gaba-gaba
Every living cell needs a continuous supply of energy to drive processes like muscle contraction, protein synthesis, and cell division. That energy comes from respiration, a set of chemical reactions that release energy from glucose. Importantly, respiration is not the same as breathing: it happens inside cells, not inside lungs.
In this lesson you will compare aerobic and anaerobic pathways, learn the word and balanced symbol equations for each, and explore how ATP acts as the universal energy currency of the cell. These reactions underpin almost every other topic in biology, and Edexcel tests them as short-answer and extended-writing questions across both papers.
Manufura
- Understand how the process of respiration produces ATP in living organisms
- Know that ATP provides energy for cells
- Describe the differences between aerobic and anaerobic respiration
- Know the word equation and the balanced chemical symbol equation for aerobic respiration in living organisms
- Know the word equation for anaerobic respiration in plants and in animals
- Investigate the evolution of carbon dioxide and heat from respiring seeds or other suitable living organisms
