Thermodynamics and Mitochondria

How do the laws of thermodynamics shape mitochondrial function and influence health and disease? This article examines how fundamental physical laws govern cellular energetics, explaining mitochondrial electron flow, membrane potential, free energy and redox balance, and their implications for inflammation, adaptation and chronic disease.

About this textbook

Every cell operates under the same physical principles that govern the universe. Thermodynamics explains how energy transformation, dissipation, and regulation determine cellular function.

This 35-page textbook develops a coherent framework linking thermodynamic laws to mitochondrial physiology and clinical relevance. Designed for advanced readers, it progressively connects physical principles to real biological processes.

Proton Motive Force — The Chemiosmotic Engine of Life

How does the proton motive force (Δp) act as the universal electrochemical intermediate of bioenergetics, linking mitochondrial respiration to ATP production, cellular signaling, and disease? This course booklet develops a quantitative framework integrating membrane potential, pH gradients, and thermodynamic constraints.

When Microglia Can’t Clean Up Their Mitochondria

Can damaged mitochondria trap the brain in chronic inflammation and drive depression?
This article explores how mitochondria–lysosome crosstalk failure locks microglia into a self-sustaining inflammatory loop, and how this mechanism connects to sepsis, T cell dysfunction, and the IRG1–itaconate axis.
