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. The mitochondrion is not merely a biological structure, but a system where 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.

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.

Mitochondria-Driven Tumorigenesis: A New View of Cancer Metabolism

Are mitochondria active drivers of cancer development rather than secondary players? This article highlights a scientific review proposing that mitochondrial bioenergetics and redox signaling may play a central role in tumorigenesis and cancer therapy strategies.

Living Systems as Dissipative Structures

How do living systems maintain order in a universe that naturally tends toward disorder?
This article explores how thermodynamic principles explain biological organization, showing how cells maintain structure and function far from equilibrium through continuous energy flow, and how this framework helps interpret metabolism, ageing, inflammation and chronic disease.
