glucose
If cells do not have immediate energy needs, they can convert glucose to glycogen for storage in the liver and muscles until it is needed. This stored glycogen can be broken down into glucose when the cells require energy.
Glucose is the simple sugar that is the primary source of energy used by our bodies during metabolism.
Carnivores obtain glucose for energy in their bodies by breaking down the carbohydrates found in the meat they eat through the process of digestion. The glucose is then absorbed into their bloodstream and used by their cells for energy.
Carbohydrates are the body's primary and immediate source of energy.

Ketone bodies originate in the liver when there is a shortage of glucose for energy production.
