Hi everyone!
Do you have an idea which organs/parts of the body are ONLY functional on glucose?
I would say the brain, pancreas, liver and kidney, but I have to take into account only those organs that are ONLY functional on glucose

Um, some of this is wrong, e.g., the brain runs well on ketones as an example.

If you google for 'which organs cannot run on ketones' gives you a very short list.

The brain can use ketone bodies in addition to glucose (in a fasting state), while the kidneys primarily use fatty acids as fuel (according to the source linked below at least). Your liver can certainly function on other things besides glucose, as it is the primary organ that generates glucose for your body. I believe the only cells that exclusively use glucose as an energy source are red blood cells since they don't have mitochondria.

All right, as an answer I'll then write red blood cells. Thank you so much!!
