Why do brain cells need glucose to function?

Answer 1

The Krebs Cycle which involves also protein metabolism. From the protein the Body extracts L-Glutamine which is technically how the body creates Glucose when one's diet is proper. Glucose is also needed for Neurotransmission which also requires B-Vitamins especially Niacin which becomes NADH which is essential for proper cellular energy production which in turn also requires the Mevalonate Highway which is the Amino Acid Grouping which creates CoEnzyme Q-10. The brain needs a little more than Glucose it also needs all the things I mentioned plus Essential Fatty Acids like DHA and Phosphatidylserine which all work together to optimize Brain function. Incidentally NADH stands for Nicotinamide Adenine Dinucleotide Hydrate one example of Coenzyme B-Vitamins one of about 13 different ones each one important for Optimum Brain Function.

Answer 2

also, glucose yields a high amount of energy in comparison to other energy sources. It can obviously also pass the blood brain barrier. However brain cells can function on alternative sources of energy such as Ketone bodies produced in the starved state.

Answer 3

All the cells in your body, need glucose to function. A cell uses it up for energy, therby providing you with energy...

Answer 4

Glucose is used by cells to change ATP into ADP, releasing the energy stored in the ATP molecule.

Answer 5

Right, it's fuel. Just as your car needs gasoline, everything in your body needs glucose, which is purified sugar.

Answer 6

glucose is the fuel of the body

Answer 7

because the brain can only digest glucose..the brain cannot digest anything else.

Answer 8

rich in carbon = rich in energy , = faster lipid processing = necessary potency to run the body .

Answer 9

duh, because glucose is their fuel - that's what provides them the energy they need to function
