The main function of oxygen in cellular respiration is to serve as an acceptor for hydrogen and electrons to produce water.
The electron is a subatomic particle with an electric charge of one elementary charge less than positive. It is represented by the symbol eor. Given that they have no known components or substructure and are a member of the first generation of lepton particles, electrons are typically regarded as elementary particles. Approximately 1/1836th of a proton's mass is that of an electron. An intrinsic half-integer value angular momentum (spin) with units of the decreased Planck constant,, is one of the electron's quantum mechanical properties. The Pauli exclusion principle states that since electrons are fermions, they can never share the same quantum state. Electrons, like all elementary particles, have the ability to interact with other particles and behave like waves when they are diffracted, similar to how light does.
