There is some weird reasoning going on here, as neuronal cells are famous for being powered anaerobically using glucose and/or ketones.
- garganzol 3y ago> neuronal cells are famous for being powered anaerobically Neurons are among the most energy-demanding cells in the body, they die the first without oxygen. Then come muscles (including heart) and liver. This means that all those cells are mostly aerobic, and only slightly anaerobic. It is true that all human body cells have an anaerobic metabolic pathway as well, but it is inefficient and cannot satisfy the energy demands for a human body to stay alive for too long without the oxygen supply.
- mpreda 3y ago> as neuronal cells are famous for being powered anaerobically using glucose and/or ketones Neurons are not famous for being powered anaerobically; if anything, they're famous for being powered exclusivelly-aerobic. AFAIK, the neurons are dependent on oxygen, thus aerobic. And unless I'm wrong, the ketones for energy is also an aerobic process. The place where we normally find anaerobic metabolism is in muscles, which are able to produce ATP using glucose to lactic acid without oxygen.
