When alcohol consumption is high, the primary pathway for the metabolism of alcohol is the ____.

When an individual is in a fed state (the time when nutrients are being absorbed) , which hormone exerts the most influence?

Fast-twitch muscle fibers are also called glycolytic because of their reliance on anaerobic energy systems.
