Bioenergetics: Anaerobic Metabolism
Anaerobic metabolism creates energy without the presence of..
pyruvate is converted to what molecule to enter the Krebs cycle
what is Acetyl-CoA?
The main substrate in glycolysis
what is glucose?
endurance and sprint training increase the hydrogen-buffering abilities of this compound
what is bicarbonate (NaHCO3)?
break down of glycogen to glucose
what is glycogenolysis?
Net ATP produced from 1 molecule of glucose in glycolysis
What is 2 ATP?
The main source of energy production in aerobic metabolism
what is the electron transport chain?
the highest energy-yielding substrate
what are lipids?
rapid repletion of phosphocreatine supports this anaerobic process
what is the ATP-PC system; phosphagen system?
glycolysis forms this 3-carbon product
what is pyruvate?
what is phosphocreatine?
electrons passing through cytochromes in the ETC are fueled by
the term for amino acids that are able to undergo gluconeogenesis
what is glucogenic amino acids?
more efficient utilization of lipids for metabolism spares
what is glycogen stores?
ATP hydrolysis creates a surplus of this molecule in the skeletal muscle
what is hydrogen?
fatigue in skeletal muscle during anaerobic exercise is caused by
what is accumulation of hydrogen?
the process in which lactate synthesized by skeletal muscle is cycled to the liver and converted to glucose
what is the cori cycle?
what is gluconeogenesis?
beta-oxidation breaks down fatty acids into subunits with this many carbons
what is 2?
adaptations are dependent on what main 2 components of fitness
what are intensity and duration?
process in which proteins are broken into smaller subunits or amino acids
what is proteolysis?
The enzyme responsible for drawing glucose from the blood into the cell to be used for glycolysis
what is hexokinase?
the electron carrier that enters the ETC first and produces more ATP
deamination of amino acids creates this by product
what is ammonia (NH3)?
maintenance of a higher intensity of exercise before switching to anaerobic metabolism is due to
what is lactate threshold?
hormone-sensitive lipase
