Document Summary
The process of making atp through oxygen phosphorylation is called chemiosmosis. Three catalytic subunits convert adp to atp as rotor turns. 2. 5-3. 3 atp made (2. 5 minimum, what we will use) Transport for nadh from glycolysis into mitochondria costs 2 atp. Total 30 atp from the aerobic metabolism o one glucose molecule. Glycolysis is nad+ limited and stops--cells die(very bad) Produces low amount of atp b/c most energy ends up in end products (lactic acid, etc) 3 carbon to 3 carbon (co2 is not made) Used in muscle cells with o2 is not available. Proteins, fats, and other carbs can be utilized. Total energy available depends on what and how much. Digestion of fats to glycerol and fatty acids. Acetyl-coa from b-oxidation of fatty acids can also be used to make ketone bodies. Under fasting, the brain switched from glycose metabolism to ketone body metabolism. Can be converted to glucose then sent thru glycolysis.
