Document Summary
Regulated by the hormones insulin and glucagon. Glucose and glycogen provide energy for exercise. If the body is low on glucose, amino acids can be turned into glucose via gluconeogenesis: but our bodies need protein to make. Organs, muscle, skin, enzymes, hormones, blood, everything. The body will steal protein from blood, organs, and muscle to male glucose if necessary. Allows for the breakdown of fat: our (cid:271)odies (cid:272)a(cid:374)"t (cid:373)eta(cid:271)olize fat (cid:449)ithout a little (cid:271)it of (cid:272)ar(cid:271)ohydrate to get it started. Condition caused by a depletion of glycogen stores in the liver and muscle. How much cho do we need: amdr: 45-65 % of our calories should come from cho, carbohydrates also has a rda of 130 g of cho per day for adults and children. Therefore, brain will seek alternative source of energy: result is ketosis. Breakdown of fat to produce ketone bodies: ketone bodies.
