Energy Systems Flashcards
What molecule provides energy?
ATP
Name the enzyme that breaks ATP
ATPase
What is ATP broken down into?
ATP —-> ADP+P+energy
How many seconds does the ATP stores last?
2-3
What system is the PC system?
Anaerobic
Name the enzyme that splits PC
Creatine Kinase
When PC gets split what are the products?
P+C+ energy
What is the energy from breaking PC used for?
attaching a P molecule onto ADP
How many molecules are produced for every PC molecule broken?
1
How long do the PC stores last for?
8-10 seconds
Name 2 sports performers the ATP-PC system would be useful for
Shot Putter
High jumper
What is the fuel source for anaerobic glycolysis?
glucose
What is glucose broken down into?
pyruvic acid
Due to no oxygen what does pyruvic acid get converted into?
lactic acid
How many molecules of ATP are produced by the lactic acid system (anaerobic glycolysis)?
2 ATP
How long can the lactic acid system last?
1-2 minutes
Name the 3 stages of the aerobic energy system
aerobic glycolysis
Krebs cycle
Electron transport chain
What is the energy source for aerobic glycolysis?
glucose
What does glucose get broken down into ?
pyruvic acid
Due to the presence of oxygen what does pyruvic acid make when it is combined with Coenzyme A
Acetyl CoA
What does Acetyl CoA combine with?
oxaloacetic acid
what does Acetyl CoA and oxaloacetic acid produce?
Citric acid
What does Krebs cycle produce?
CO2
Hydrogen
2ATP
What does hydrogen combine with?
oxygen
How many molecules of ATP does the aerobic energy system produce?
36-38
