5. Explain five ways the body tries to maintain an uninterrupted flow of energy, and the sequence in which various nutrients are used to supply energy. (page 47)

-Glycogen and body fat are used for energy
-Glycogen stores are limited -Body fat stores are unlimited, but brain and nerves cannot use fat as energy source -When deprived over longer period, brain can use some ketones for energy, but needs a minimum amount of -glucose -Only source of glucose then is protein (dietary or own muscle tissue) – breakdown Protein-sparing Effect – adequate carbohydrate can prevent breakdown of protein in the body. |
