Reference: AQA
A continuous process occurring in every living cell that transfers energy from chemical stores in glucose to power vital cellular activities.
Process in which absorbed biomass is oxidised to supply ATP for muscle contraction and heat, with mass lost as carbon dioxide and water.
A set of enzyme-controlled reactions that transfer energy from glucose and other respiratory substrates to ATP and heat.
Oxygen is needed for aerobic respiration, and glucose is the fuel respired to release energy for muscle contraction.
A universal chemical process, continuously occurring, that supplies ATP in all living cells.
The process in which some glucose is used to release energy for cells.
