Chapter 8: Exercise Metabolism And Bioenergetica Flashcards
What does the body need in order to properly function and meet the demands of exercise
Energy
What is the energy molecule that is used to do cellular work? How is it attained?
Adenosine triphosphate
It is attained through food substrates in a diet
What is the first law of thermodynamics
Energy that cannot be created or destroyed only converted from form into another
What metabolic process breaks carb into glycogen which then produces ATP ?
Glycolysis
What metabolic process takes free fatty acids from the breakdown of stored or consumed fats? The free fatty acids uses oxygen to create ATP
Aerobic pathway
What is by product of protein when digested or broken down?
Amino acids
Amino acids can be metabolized by which metabolic pathway?
Oxidative phosphorylation
Is oxidative phosphorylation safe?
No, it uses amino acids which are also the building blocks for building muscle mass
What are ketone bodies?
They are produced by the liver when there is a low amount of energy intake or low carb availability
What metabolic pathway uses ketone bodies?
They are oxidized by the oxidative phosphorylation pathway to create ATP
What are the two factor to exercise?
Intensity and duration. There’s a inverse relationship between the two
What does the body need in order to carry out exercise?
It needs fuel which is gathered by food that’s broken down by chemical reactions to provide energy and heat
What metabolic pathway is the fastest and easiest to give ATP?
ATP-PC . How ever it only give short amount duration activity due to the lack of PC
What anaerobic pathway generates ATP but not a lot ?
Glycolysis is both aerobic and anaerobic. Glycolysis creates pyruvate and ATP. Under anaerobic conditions the pyruvate created can cause lactic acid.
What metabolic pathway process ATP from oxygen and runs kinda slow
Oxidative phosphorylation
