Can-Fit-Pro PTS CH3) Bioenergetics Concepts (Questions + Answers) Verified 100% Correct!!.

Bioenergetics - Answer-The study of how energy flows in the human body Energy - Answer-The ability to do physical work Metabolism - Answer-Sum of all chemical reactions in the body that either use or create energy Catabolic process - Answer-- Large molecules are broken down into smaller ones - Digestion of food Anabolic process - Answer-- Cells build larger molecules from smaller ones - Use of amino acids to build muscles Adenosine Triphosphate - Answer-ATP Adenosine~P~P~P - Answer-Molecular structure of ATP ATP - Answer-Chemical compound made up of adenosine and three phosphate molecules ATP - Answer-Energy currency of the body Systems that produce ATP - Answer-- ATP-CP (creatine phosphate) system (anaerobic system) - Lactic acid or glycolytic energy system (anaerobic system) - Aerobic or oxidative energy system Creatine Phosphate - Answer-CPAnaerobic system - Answer-What system uses the ATP-CP system? Anaerobic system - Answer-What system uses the Lactic acid or Glycolytic energy systems? Anaerobic system - Answer-- Operates without the use of oxygen - Limited and inefficient - Provides most of the energy at the start of the exercise Aerobic system - Answer-- Operates using oxygen - Very efficient because it uses an abundant supply of fat and carbohydrates to create ATP to fuel activity Rating of Perceived Exertion - Answer-RPE Heart Rate Reserve - Answer-HRR RPE - Answer-Used to measure the intensity of your exercise RPE - Answer-AKA The Borg Scale RPE - Answer-Range from 6 - 20 Follows the general heart rate of a healthy adult by multiplying by 10 HRR - Answer-The difference between a person's measured or predicted maximum heart rate and resting heart rate Anaerobic metabolism - Answer-- ATP created through a chemical reaction that does not require oxygen - Activity so intense that the body cannot get oxygen to the muscles fast enough, so ATP is created without itATP-CP Phosphagen System - Answer-Provides fuel for up to 10 seconds at maximal activity Phase 1 of ATP-CP Phosphagen System - Answer-- Stored ATP - Fuel for 1-2 seconds at maximal effort ADP + P + Energy - Answer-ATP-CP Phase 1 - ATP splits into: ___ + ____ + _____ Adenosine Diphosphate - Answer-ADP Phase 2 of ATP-CP Phosphagen System - Answer-- Creatine Phosphate - The Phosphagen System - CP splits to provide energy to re-form ATP from ADP - Rapidly forms ATP from high energy phosphates, allowing the muscle to keep contracting until the ATP and CP levels decline to the point that the body must slow down and draw upon the lactic acid system to continue ATP + Creatine - Answer-ADP + CP --- ___ + _______ with the help of Creatine Kinase 10 seconds - Answer-Total amount of stored ATP and CP is limited to approximately __ seconds of intense effort Glycolytic system - Answer-Provides fuel for up to two minutes at maximal intensity Glycolytic energy pathway - Answer-Series of 10 enzymatically driven reactions that cause the breakdown of carbohydrates in the form of glycogen stored in the muscle cell or glucose found in the blood taking place in the cytoplasm of the cellGlycolytic energy pathway - Answer-Results in the reduction of pyruvate to form a cellcular byproduct called lactic acid 2 - Answer-Glycolytic system - From gluclose, __ ATP molecules are produced 3 - Answer-Glycolytic system - From glycogen, __ ATP molecules are produced 2ATP + 2LA + heat - Answer-Breakdown of glucose Lactic acid - Answer-As more glucose is metabolized, more ____ _____ is produced Lactic acidosis - Answer-Lactic acid levels causing temporary muscle failure (no contraction can occur) Glycolysis - Answer-Prime p
