Approximately how much total glycogen is stored in the body under normal conditions? A. 800-1000 g (mostly in the liver) B. 100-150 g (all in muscle) C. 300-400 g (mostly in muscle and liver) Answer in the poll, then explain your rationale below in the comments! I'll follow up with my breakdown of the question after enough people have responded. From Chapter 3: Bioenergetics of Exercise and Training DCO Code: 1.E1 NOTE: Image is for illustration purposes, not needed to answer the question.
