All metabolic functions in the body require ATP to proceed. ATP is the energy currency of the cell; all other energy sources must first be converted to ATP before they are able to yield energy.

All organs can convert glucose to ATP for use as energy, except for the brain. The brain is the only organ that cannot use other energy sources for fuel (fats, proteins, fructose, glycogen, etc).

ONE EXCEPTION: is that the brain can run on ketones during starvation.

My degree is in Kinesiology, not physiology, and I'm answering this off the top of my head, so use this answer for informational purposes only.

Just to add a little; fatty acids cannot pass the blood brain barrier, so only glucose can be used by the brain. Red blood cells don't have a mitochondria, so they also rely solely on glucose. The kidney medulla, lens of the eye, and tests have very little mitochondria, so they depend almost entirely on glucose.

The brain and spinal cord use only glucose as their energy source. This is why people will pass out with hypoglycemia.

What is the main fuel for the body's cells?

The main fuel for the body's cells is glucose. Glucose because the brain relies solely on glucose as it's source for fuel. Secondly, oxygen because of its role in cellular respiration, which also uses glucose to produce energy in the form of ATP. ATP is an abbreviation for adenosine triphosphate, and all organisms from the simplest bacteria to humans use ATP as their primary energy currency. ATP is a form of energy that the cells can use to power all their activities.. but the fuel is Glucose.


Name the fuel the human body burns?

The preferred fuel source for the body is glucose.


When a cell needs energy's does it breaks down the chemical glycogen?

Glycogen is made and stored in the cells of the liver and muscles until it is needed for energy. Glycogen phosphorylase is the primary enzyme of glycogen breakdown into glucose. Glucose derived from liver glycogen is the primary source of blood glucose used by the rest of the body for fuel.


Is fat is the primary fuel for the brain?

Glucose is the only fuel normally used by brain cells. Because neurons cannot store glucose, they depend on the bloodstream to deliver a constant supply blood glucose. A process called glycogenolysis can break down glycogen stored in the liver to glucose. This then travels in the blood to your brain or muscles in need of glucose.


What molecule is the major fuel used by cells?

In energy metabolism glucose is king. It is the primary product of photosynthesis and it is the energy molecule f choice for life across kingdoms.

Glycogen to glucose?

Glycogen is a storage of energy within the body, and glucose is the primary form of energy. So for example, if your body requires glucose to survive, when it has plentiful amounts. Your body converts glucose into glycogen for storage. However, if your body has low amount of glucose within it. Your body will rely on the storage of glycogen to break down into its components and use the glucose for fuel.


What is the primary fuel for the brain in-between meals?

Glucose assuming you have normal hours in between meals. Your livers and muscles have glucose stores (glycogen) that fuel the hours in between meals.
