Answer :
The o2 required for cellular respiration is furnished by breathing.
Cellular respiratory is a series of chemical reactions that break down glucose to produce ATP, which can be used as strength to electricity many reactions in the course of the frame. There are three most important steps of cell respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation.
Cellular respiratory is the process by using which organic fuels are oxidized in the presence of an inorganic electron acceptor along with oxygen to produce big quantities of energy, to force the bulk manufacturing of ATP. mobile breathing is the procedure with the aid of which food, in the shape of sugar (glucose), is converted into electricity within cells.
Cellular respiratory is the manner via which cells in plants and animals destroy down sugar and flip it into electricity, which is then used to perform work on the cellular level. The purpose of mobile breathing is easy: it offers cells the electricity they want to function.
