5. Popular «energy drinks are nonalcoholic carbonated beverages. Advertising emphasizes that they increase working capacity. Most beverages contain caffeine and its analogs, theobromine and theophylline (vegetable alkaloids), vitamins, casily digestible sugar (glucose, sucrose), taurine, carnitine. These drinks are highly carbonatcd, which accelerates their absorption into the blood. Why do energy drinks improve efficiency? For answer: a) draw a diagram of the glycogen metabolism pathway with its the acceleration possibly contributing to better efficiency; b) indicate the mode of caffeine action on the rate of this process, if it is known that it inhibits phosphodiesterase; c) cxplain why 3-4 hours after the taking of «cnergetics» fatigue and drowsiness оссur.
