Document Summary
Glycogen in liver: immediate tissue, effected by fasting and sleep. Youthsports: need carbs to re-up liver glycogen, important during stretches of physical. Liver releases glucose into blood to maintain homeostasis activity for consecutive days: tournament, high school sports. Endurance athletes: 60-75% complex carbs to feed skeletal muscle: complex carbs: made up of sugar molecules, examples: vegetables, peas, beans, whole grains. Important for high intensity bursts of physical activity. Oxygen not needed to carry out production of atp. Produces atp through oxidative phosphorylation transfer of electons and adding to adp. In mitocondria: adp (di) + electron= atp (tri) Lipp(cid:373)a(cid:374),(cid:1005)94(cid:1004): atp is (cid:272)o(cid:374)tai(cid:374)ed i(cid:374) the (cid:271)o(cid:374)ds, that"s (cid:449)here e(cid:374)erg(cid:455) (cid:272)o(cid:373)es fro(cid:373), Mysoin atpase splits atp (found in skeletal muscle) to adp: large amount, usually in fast twitch fibers (type2) Review: type 1 fibers more aerobic, more mitocondria. Produces 7-10 kcals per 1 mole atp. Average sized: 20-30 pounds muscle holds 4-8 ounces atp. Adp phosphorylated (phosphate added) into atp inside muscle cell.
