Various reactive oxygen species, such as singlet oxygen, peroxynitrite and hydrogen peroxide, must be continually removed from cells to maintain healthy metabolic function.

In spite of its resistance to being cultured, at least one potentially significant metabolic function can be inferred through circumstantial evidence: nitrogen fixation.

Your body will need 2,000 calories a day to carry out its metabolic functions.

Nerve damage causes the metabolic function of the cell to change from that of producing molecules for synaptic transmission to that of producing molecules for growth and repair.

We know that during sleep the body's important metabolic functions are restored and repaired.
