Respiration is a Chemical Reaction

  • Aerobic respiration requires oxygen and is defined as the chemical reactions in cells that use oxygen to break down nutrient molecules to release energy

  • It is the complete breakdown of glucose to release a relatively large amount of energy for use in cell processes

  • It produces carbon dioxide and water as well as releasing useful cellular energy

Examiner Tips and Tricks

There are usually 3 marks given for the aerobic respiration chemical equation in an exam:

  • one for getting the correct formula for glucose and oxygen

  • one for getting the correct formula for carbon dioxide and water

  • one for balancing the equation correctly

So make sure you can do all three to gain maximum marks!

Absolutely brilliant, both my girls used it for A levels and GCSE. It's saves on paper copies, also beneficial exam questions ranked from easy to hard. It's removed a lot of stress from the exams.
