The R/ETS ratio: Where we are now

Abstract

The relationship between respiration and the activity of the electron transport system (ETS) is an unresolved issue that begs more understanding, because measuring ETS activity or its equivalent, potential respiration, is the fastest and most synoptic way of assessing respiration (R ) in ocean space. Furthermore, this topic is an entry point to the understanding of respiratory control. As we know from the variability in respiration measurements, in Kleiber’s Law, and in past R/ETS studies, many factors can alter respiration. Temperature, nutrient limitation, age, size, temporal periodicity, and activity levels are among these factors. To model or to measure respiration accurately, these factors need to be understood.
