glucose + oxygen --> carbon dioxide + water (+ energy)
Respiration releases energy which is vital for all cells
Respiration occurs in mitochondria. Mitrochondria have folded inner membranes which means that there is a larger surface area where the enzymes that control cellular respiration are found.
The energy released in respiration is used for:
- Synthesis reactions - building up large molecules from smaller ones to make new cell material
- Muscular activities - ie making muscles contract
- Maintaining a constant body temperature - this means that the temperature of our bodies is always the same temperature regardless of the surroundings
- Releasing energy from food so that the cells of the body can use it
