Why Your Cells Cannot Make Energy Without Oxygen

Every cell in your body depends on oxygen, largely because your mitochondria need it to efficiently produce energy. This clip explains why oxygen deprivation, or hypoxia, is such a powerful form of cellular stress and why studying how cells respond to low oxygen can reveal so much about the body’s broader stress response.

What If Parkinson’s Is Also An Energy Metabolism Problem?

Parkinson’s is often framed around dopamine, but this clip looks deeper at what may be happening inside the cell. Oxidative stress, inflammation, chronic infection, and environmental toxins can interfere with key thiamine-dependent enzymes involved in energy production, including pyruvate dehydrogenase and alpha-ketoglutarate dehydrogenase. That raises a bigger question about whether impaired B1-dependent metabolism is part of the disease process itself.
