Enzymes
Enzymes do not cause the reaction to take place it just speeds up the chemical reaction. True or False
True
Glycolysis needs oxygen to function. True or False
False
True or False?
Aerobic Metabolism DOES NOT provide more overall energy (ATP) than Anaerobic Metabolism.
False (if you got that wrong you need to study smh)
Anaerobic Metabolism is used for what type of activities?
High intensity and short duration activities such as sprints, weightlifting, and HIIT training.
All energy needed that is provide by aerobic metabolism
Steady state
PFK is a rate-limiting enzyme. True or False
True
What is the Net ATP made from glycogen?
3 ATP
During the end of the ETC what acts as the final hydrogen and electron acceptor?
OXYGEN
Anaerobic Pathways uses both triglycerides and carbohydrates as energy
True or False?
False
Anaerobic Pathways only use carbohydrates as energy.
Oxygen taken in above resting values after exercise
oxygen debt
What is the enzyme needed for the ATP-PC system?
Creatine kinase
What 3-carbon compound is the final product of glycolysis?
Pyruvate
What substrates can the aerobic pathway use?
Triglycerides, Carbohydrates, and even Protein
Where does anaerobic and aerobic metabolism occur within a cell?
Anaerobic metabolism occurs in the cytoplasm
Aerobic metabolism occurs within the mitochondria
The difference between the amount of oxygen actually consumed during exercise and what would be consumed if energy demands meet solely through aerobic metabolism
Oxygen deficit
What is a rate limiting enzyme?
The rate at which the entire reaction occurs depends upon the rate at which that particular enzyme works
Where does glycolysis occur?
Besides the ETC what is the other major Enzymatic System for Aerobic Metabolism and what is its function?
The Krebs Cycle (aka the Citric Acid Cycle)
Function: oxidize substrates
True or False?
Aerobic and Anaerobic metabolism are both present at any given time.
True
Another term for oxygen debt, represents the energy “borrowed” from anaerobic metabolism to perform exercise
Excess postoxygen consumption (EPOC)
What are the three main enzymes for glycolysis?
Glycogen phosphorylase
Phosphofructokinase
Lactate hydrogenase
What is the aerobic and anaerobic product of glycolysis?
Aerobic: pyruvate
Anaerobic: lactate
What is the function of the ETC that produces the majority of ATP during aerobic metabolism called?
Oxidative Phosphorylation
The magnitude of contribution of each system is primarily dependent on the _______ of the activity and secondarily on the _______.
intensity, duration
True or False: EPOC is higher with anaerobic and intense exercise
True; due to anaerobic metabolism, elevated temperature, and hormones
