Hormones and Stress

Mitochondria respond to thyroid hormone but the article does not identify thyroid hormone as made in mitochondria. Mitochondria in adrenal glands produce cortisol, while mitochondria in testes and ovaries produce sex hormones. Mitochondria produce important hormones including sex hormones and stress hormones. Stress physiology can be understood as involving energy demand, energy availability, and mitochondrial signaling. Psychological stress is associated with increased vulnerability to illness such as catching a cold.
