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.

"Assuming a publication charge of € 1200 per article, scientists mentioning mitochondria or photosynthesis pay € 100 000 every day in 2021 for ‘selling’ their output to publishers ― over € 36 Mill per year."

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.

Paywall journalism is the opposite of Open Access.

Though often defined from the individual reader's perspective, a paywall can also apply to an institution (such as a library) or the author.
