ESS 3 Lecture Notes - Lecture 13: Phosphocreatine, Acetyl-Coa, Phosphagen
Document Summary
Atp (adenosine triphosphate: released during breakdown of glucose, fatty acids & amino acids, 3 phosphate groups, provides energy for all cell activities, coupled reactions (use energy) Creatine phosphate (cp): stores some energy that can be used to make atp. Lactic acid: by-product of glycolysis, contributes to fatigue but not only factor, may be a factor of muscle soreness during exercise, # of mitochondria plays a role in buildup of lactic acid (endurance exercise can increase. # of mitochondria in muscle cell: lactic acid transported to liver where it"s converted to glucose (cori cycle) Can be maintained longer with higher yields of atp: uses pyruvate generated by glycolysis & fatty acids released from its triglycerides, critical for endurance exercise performance, triglyceride (fats) can be metabolized to generate atp. Provide 2x as much energy per gram as carb (9) Provide a lot of acetyl coa to release energy or combien to make body fat.
