|| BEC tutorial: Find out the straight (yet enigmatic) connection between Gibbs energy G [J] and the 'molar Gibbs energy' of a transformation [J·mol-1], which is better called the Gibbs force:|
||How does proficiency testing help achieve quality and reproducibility? |
Providing a pre-established set of testing criteria improves and standardizes technical performance.

|| BEC tutorial: Did you know that a cell respiring O2 at 100 amol·s-1·x-1 consumes 60 million O2 molecules per second per cell? |
Apply the Avogadro constant and SI prefixes: 100 (amol O2)·s-1·(x cell)-1 = 60.2·106 (x O2)·s-1·(x cell)-1
|| Why do we perform multiple H2O2 calibrations in the Amplex® UltraRed assay?|
The sensitivity to H2O2 of the fluorometric signal changes during the experiment as a function of: (1) experimental time and accumulating UltroxRed (similar to resorufin), (2) changes of the optical properties due to titrations, and (3) the radical scavenging capacity of the sample. Therefore, H2O2 calibrations are performed before and after sample addition, and after selected titration steps.

|| What are the substrate-uncoupler-inhibitor titration reference protocols?|
These protocols provide a common baseline for comparison of mitochondrial respiratory control in a large variety of species, tissues and cell types, mt-preparations and laboratories.

||The central role of the Q-junction in mitochondria|
The Q-junction is a point of convergence in the electron transfer system. Electrons flow from different dehydrogenases and respiratory Complexes into the Q-junction and then downstream to Complex III.
