cellular respiration

cellular respiration

n.
The series of metabolic processes by which living cells produce energy through the oxidation of organic substances.

cellular respiration

or

cell respiration

a catabolic process (see CATABOLISM) occurring in cells where complex organic molecules are broken down to release energy for other cellular processes. Cell respiration usually occurs in the presence of oxygen (see AEROBIC RESPIRATION) but some organisms can respire without oxygen (see ANAEROBIC RESPIRATION).

CO induces toxic effects by tightly binding to hemoglobin to form COHb and reducing the oxygen-carrying capacity of blood; by binding with mitochondrial cytochrome oxidase, CO also interferes with cellular respiration (1 Because CO can induce toxicity through different pathways and because COHb levels begin to decrease as soon as exposure ceases, COHb levels indicate exposure but do not correlate consistently with either symptoms or prognosis.
