Glycolysis
The substrate that initiates glycolysis
What is glucose?
The type of system ATP-PC is
What is anaerobic?
Another name for the krebs cycle
What is the citric acid cycle?
Since the ETC uses oxygen, it is an example of this kind of system
What is aerobic?
The difference between amount of oxygen actually consumed during exercise and what would be consumed if energy demands met solely through aerobic metabolism
What is oxygen deficit?
The part of the cell glycolysis takes place in
What is the sarcoplasm of muscle cells?
The enzyme that breaks PC into creatine and Pi
What is creatine kinase?
The function of the krebs cycle
What is to oxidize substrates?
The function of the ETC
What is to produce the majority of ATP during aerobic metabolism ?
When all energy needed is provided by aerobic metabolism
What is steady-state?
What is two pyruvate molecules, two NADH + H, and two ATP molecules?
When breakdown of PC occurs, this type of recovery period is necessary to provide energy to reform PC
What is aerobic
The 4-carbon molecule that is formed in the last reaction of the krebs cycle
What is oxaloacetate?
This molecule acts as the final hydrogen and electron acceptor at the end of ETC
What is Oxygen?
When oxygen taken in is above resting values after exercise
What is oxygen debt?
The rate limiting step for glycolysis
What is Phosphofructokinase (PFK)?
ATP-PC usually provides energy for this period of time during intense exercise
What is 30 seconds?
Acetyl-CoA combines with oxaloacetate to form this 6-carbon molecule
What is citrate?
The net ATP for glucose and glycogen
What is 32 ATP for glucose and 33 ATP for glycogen?
The improved description of oxygen debt as representing the energy “borrowed” from anaerobic metabolism to perform exercise
What is excess post oxygen consumption or EPOC
This molecule can accept hydrogens to become lactate if aerobic metabolism doesn't accept hydrogens.
What is pyruvate?
The primary cause of decreased muscle force and fatigue
What is increased acidity and accumulation of Pi?
The products that come from citrate going through a series of reactions
What is 2 CO2 and 1 ATP
Energy released by passing electrons is used to pump these ions from the inner to the outer compartment of mitochondria through the pump complexes
What is hydrogen ions?
The benefit to active recovery after intense exercise
What is it decreases blood lactate faster than passive recovery?
