Precision Nutrition Ch 3 Energy Transformation & Metabolism Exam 2024

Precision Nutrition Ch 3 Energy Transformation & Metabolism Exam 2024 Law of Thermodynamics -Answer-energy cannot be created or destroyed, only transformed Energy transfer -Answer-movement of energy fromone compound to another so that it can be used What is ATP -Answer-energy currency of the body Hepatocytes -Answer-liver cells Mycoyte -Answer-muscle cells Adipocyte -Answer-fat cell Two most important "raw Materials" for making atp -Answer-1. triglycerides 2. glycogen triglycerides -Answer-raw material for production of atp, storage form of fatty acids, kept in adipocytes and some myocytes glycogen -Answer-raw material for production of atp, storage form of carbohydrate, kept in mycocytes and hepatocytes Amino acid pool -Answer-AA available for protein synthesis at any given time in the body What is the molecular structure of ATP -Answer-ATP is an adenosine molecule with three phosphate molecules attached What bond holds the ATP molecule together -Answer-covalent bonds What bonds hold together carbs, fats and proteins -Answer-covalent bonds Breaking covalent bonds releases what -Answer-energy What happens to ATP when energy is needed -Answer-break in an one adenosine phosphate bond leaving an ADP with one free phosphate 3 main processes of ATP systems -Answer-1. ATP-pcr system-10-15s of energy 2. glycolytic pathway-1-2 min 3. Oxidative Phosphorylative pathway ATP/PCR System -Answer-composed of ATP and phosphocreatine, this system replenishes energy rapidly without the use of oxygen -operates in the cytosol -uses enzyme creatine kinase to break bonds between creatine and phosphate that are joined in the PCr molecule (phosphocreatine) -this bond break releases energy -free phosphate rejoins ADP to make ATP and use more energy Why does supplementing creatine help performance -Answer-because with more creatine in the muscles, more creatine and Pcr is av
