Energy drinks have essentially the same properties as coffee or green tea. BUT thanks to the presence of CO2 and taurine, caffeine is absorbed into the blood faster and the effect is quicker.
Like coffee with sugar. Caffeine excites the nervous system, and glucose is the fuel for this very system, which, being in an excited state, consumes more fuel than usual.
An excited nervous system means more active brain cells, faster signals, reflexes, and motor activity.
Stimulating the internal reserves of the body. For example, it is known that glucose, like other carbohydrates, is rapidly absorbed into the bloodstream, is involved in oxidative processes and delivers energy (carbohydrates) to the muscles, brain and other vital organs. Like any stimulants, they act according to a simple scheme - to take a lot of energy from the body at once, which leads to inevitable exhaustion of the nervous system, metabolic disorders.
