It happens all of the time, except when you are sprinting. It then switches to fermentation, which doesn't use oxygen. This is because when you are sprinting, you don't get enough oxygen for cellular respiration to occur.
cellular respiration
Hippies ;)
Glycolysis
oxygen is added to the atmosphere when plants take in carbon dioxide during cellular respiration
They are utilized later. Used in respiration mainly
The general term is cellular respiration.
glucose is changed into pyruvate
glucose is changed into pyruvate
fermentation
It is breathed out of the body by the lungs
Cellular respiration takes place in the mitochondria of the cell. It is the process where cells convert glucose into ATP (energy) through a series of biochemical reactions.
Everyone and it happens because our body needs energy.
