Exercise Metabolism Flashcards
_____________ reactions capture energy (ATP) from the breakdown of energy-rich fuel molecules.
Catabolic
What are the 3 stages of Catabolism?
- Hydrolysis of complex molecules
- Conversion to simple intermediates
- Oxidation of Acetyl CoA
for a catabolic reaction, what is hydrolysis of a complex molecule do?
Complex molecules are brown down into their simple building blocks
What are the simple building blocks for
- Proteins
- Polysaccarides
- Triacylglycerols
- Proteins: Amino Acids
- Polysaccarides: Monosaccarides
- Triacylglycerols: Free Fatty Acids and Glycerol
For the 2nd stage of Catabolism, what does the conversion of simple intermediates mean?
The diverse building blocks are further degraded to acetyl CoA and a few other simple molecules. A small amount of energy is captured as ATP
For the 3rd stage of Catabolism, what does Oxidation of Acetyl CoA mean?
The Citric Acid cycle is the final common pathway in the oxidation of fuel molecules.
Acetyl CoA ==> ______________
2 CO2
NAD+ -> NADH -> _____________
FAD -> FADH2 -> _____________
Oxidative Phosphorylation
What are the 3 primary pathways of ATP production?
- Phosphate System
- Glycolysis Metabolism
- Mitochondrial Respiration
Describe the pathway for Carbohydrates to be converted to energy
CHO->Simple Sugars->Glucose->Glycolysis->Pyruvate
->Acetyl CoA->Citric Acid Cycle->Oxidative Phosphorylation-> ATP
_____________ is the most rapid way to regenerate ATP and is catalyze by Creatine Kinase (CK) and is part of the phosphate system
CrP
CrP + ADP <=> ?
ATP to Cr
_____________ is crucial to the muscle’s ability to tolerate increased metabolic demand.
Phosphogen system
The phosphagen system produces _____________ at a high rate as well as molecules AMP, Pi, ADP, that stimulate Glycogenlytic, Glycolytic, and mitochondrial respiration pathways
ATP
Glycolysis begins with _____________ or _____________
Glucose or Glycogen
