Регуляция энергетического обмена

Биохимический процесс усвоения пищи и образования АТФ должны постоянно приспосабливаться к изменению энергетических потребностей клеток. Необходимость согласования производства и потребления АТФ следует уже из того факта, что суммарное содержание коферментов в организме незначительно. Калорийность суточного рациона человека составляет примерно 12 000 кДж (см. Питание. Органические вещества). При к.п.д. 50 % такая энергия достаточна для образования 120 молей АТФ, то есть примерно 65 кг. Однако в организме человека содержится всего 3-4 г свободных адениновых нуклеотидов (АМФ, АДФ и АТФ). Следовательно, каждая молекула АДФ должна ежедневно тысячекратно фосфорилироваться в АТФ и вновь дефосфорилироваться.
