Iron supply has been suggested to influence phytoplankton biomass, growth rate and species composition, as well as primary productivity in both high and low NO3 − surface waters. Recent investigations in the equatorial Pacific suggest that no single factor regulates primary productivity. Rather, an interplay of bottom-up (i.e., ecophysiological) and top-down (i.e., ecological) factors appear ...

Cellular Respiration - an overview | ScienceDirect Topics

Cellular respiration sustains aerobic life and involves the oxidation of nutrients, with the final production of carbon dioxide and water. During this process, oxidation energy is captured in the form of adenosine triphosphate (ATP) molecules. Most of the oxygen is reduced to water by cytochrome c oxidase in a four-electron process. However, a small percentage of oxygen (1–3%) can be ...
