Activity of the electron transport system was 0.04 and 0.03 [micro]L [O.sub.2] x [h.sup.-1] x [mL.sup.-1] at Marica and Guarapina Lagoons, respectively.
Activities of esterase enzymes and of the electron transport system have been employed as indicators of microbial metabolism, in aquatic or terrestrial systems (Trevors, 1984; Houri-Davingnon and Relexans, 1989; Stubberfield and Shaw, 1990).
This particular electron transport system
is not complete, and each molecule of NAD releases only enough energy to make 2 ATP (a total of 4).

At the mitochondrial level, the synthesis and degradation of the macroenzymes of the electron transport system (ETS) is a function of the respiratory requirements of marine organisms (Owens & King 1975).
The activity of the electron transport system decreased significantly in oyster exposed to sulphide for 10 days.
Where in the cell is the electron transport system
Respiratory chain: The electron transport system
located in the mitochondria, in which electrons released by NADH are passed on to a series of other molecules that first accept the electrons and then pass them on to the next molecule in the chain.
The rationale for studying coenzyme [Q.sub.10] stems from the fact that statins reduce not only production of cholesterol but also biosynthesis of coenzyme [Q.sub.10], or ubiquinone, a component of the electron transport system
and a key player in mitochondrial ATP production.
The rationale for studying coenzyme [Q.sub.10] stems from the fact that all statins not only reduce production of cholesterol but also reduce the biosynthesis of coenzyme [Q.sub.10], or ubiquinone, a component of the electron transport system
and a key early player in mitochondrial ATP production.
Compared with unrestrained plants under the same lights, the test plants showed marked destruction of chlorophyll and decreased activity within the electron transport system
that converts sunlight into energy for the plant.
