Metabolic changes during exercise Flashcards
thaxter
ATP is NOT stored in skeletal muscle; True or False?
True
What does the rise in metabolism depend on?
The cross-bridge cycling rate of myosin and actin
Substrate availability
Accumulation of metabolic byproducts
At rest the body produces ATP by aerobic metabolism by the catabolism of?
Glucose or fatty acids (primarily)
How much fuel is contributed by fats through beta oxidation
2/3
1/3 fuel is contributed by carbohydrate; which process facilitates that
aerobic glycolysis
What are the sources of energy during exercise
Alactic Anaerobic Source- ATP and creatine phosphate (CP)
Lactic anaerobic source- Glucose from stored gylcogen in the absence of oxygen
Aerobic source- Glucose lipids, proteins in the presence of oxygen
All energy source processes start at the same time; True or FALSE
True
