Mitochondria contain several flavin-dependent enzymes that can produce reactive oxygen species (ROS). Monitoring ROS release from individual sites in mitochondria is challenging due to unwanted side reactions. We present an easy, inexpensive method for direct assessment of native rates for ROS release using purified flavoenzymes and microplate fluorometry.

The energy released from the breakdown of the chemical bonds within nutrients can be stored either through the reduction of electron carriers or in the bonds of adenosine triphosphate (ATP). In living systems, a small class of compounds functions as mobile electron carriers, molecules that bind to and shuttle high-energy electrons between compounds in pathways. The principal electron carriers that will be considered originate from the B vitamin group and are derivatives of nucleotides; they are...

A nicotinamide adenine dinucleotide (NADH)-coupled ATPase assay has been adapted to semihigh throughput screening of small molecule myosin inhibitors. This kinetic assay is run in a 384-well microplate format with total reaction volumes of only 20 µL per well. The platform should be applicable to virtually any ADP producing enzyme.
FAQs
NADH production occurs at several points in nutrient breakdown, including glycolysis, pyruvate oxidation, and the citric acid cycle. These stages act on different metabolic intermediates, so their contributions reflect the progression from glucose breakdown to further oxidation of pyruvate-derived molecules. Considering the stages together helps researchers relate NADH generation to the overall flow of cellular respiration.
Enzymes transfer hydrogen or electrons from metabolic intermediates to NAD+, reducing it to NADH. This reversible carrier relationship connects oxidation reactions with subsequent electron delivery. Tracking the relative production of NADH and availability of NAD+ can therefore provide information about redox balance, a cellular state that reflects how electrons are being generated and transferred during metabolism.
After formation, NADH delivers high-energy electrons to the mitochondrial electron transport chain. Electron transfer through protein complexes drives proton pumping, establishing the process that supports ATP synthesis through oxidative phosphorylation. This connection explains why changes in NADH production can influence interpretations of cellular energy conversion, even though NADH itself is an electron carrier rather than ATP.
NADH production captures electrons from metabolic intermediates, whereas ATP synthesis uses the energy associated with electron transfer through the mitochondrial electron transport chain. The two processes are therefore linked but not identical: NADH carries reducing power generated during metabolism, and oxidative phosphorylation uses that electron flow to support ATP formation. Separating these stages clarifies measurements of cellular respiration.
Measuring NADH production provides an indication of metabolic activity and cellular respiration because the molecule is generated during glycolysis, pyruvate oxidation, and the citric acid cycle. Researchers can also examine changes in NADH-related signals when metabolism is altered. These measurements help evaluate electron flow, redox balance, and energy-conversion behavior without treating ATP output as the only metabolic result.
Changes in NADH production can reveal differences in cellular respiration, metabolic activity, and redox balance across biological conditions. For that reason, researchers apply NADH measurements or manipulation when examining disease-associated changes, responses linked to exercise, and metabolic processes used in biotechnology. The same readout can thus connect fundamental electron transfer with broader biological or engineered-system questions.
