This month we will explore how the mitochondria regulate energy production through the balance of the CoQH2/CoQ ratio and what this reveals about respiratory chain efficiency.

How does the electron transport chain sense metabolic stress and adapt to changes in fuel availability? Can the CoQH2/CoQ ratio act as a signaling mechanism that links mitochondrial function, cellular metabolism, and oxidative stress?

Martínez-Reyes et al. explore these questions by examining how the CoQH2/CoQ ratio serves as a metabolic sensor of respiratory chain efficiency and mitochondrial redox state.
