Definition

At cell level, respiration is the process in which biological systems oxidize different substrates, where the oxidizing agent is a substance that is external to the system itself. Historically, the term has been used when the substance which is the external  electron acceptor is oxygen ( aerobic respiration). However, this definition should be widened to include the cases where the external electron acceptor is a substance other than oxygen (anaerobic respiration).

Overview

Respiration is a common way for living organisms to obtain energy. The process is a source of oxidation for various cellular components, such as NADH, succinate, acyl-CoA, etc., which are produced either by the catabolism of substances taken from the exterior or directly from a component taken from the exterior, such as methanol (this is the case for Paracoccus denitrificans, which can grow on methanol) or Fe 2+ (in the case of Acidithiobacillus...
