The following notes are from this review paper written by Iñigo San-Millán. Enjoy!
Resting conditions (fatty acids & carbohydrates) — Transported — > mitochondria –> oxidized to Acetyl-CoA –> Posterior oxidation in the Krebs cycle and electron transport chain (ETC) <– This is called oxidative phosphorylation (OXPHOS) –> creates Adenosine triphosphate (ATP) energy currency of the body.
Interesting note: Mitochondria are the production site for reactive oxygen species – signaling molecules needed for homeostasis.
“Hence, mitochondrial malfunctions will impact cellular bioenergetics, cellular function, and cellular homeostasis, making mitochondria a key player in health and disease.”
