Energy Systems Flashcards
What does ATP stand for?
Adenosine Triphosphate
How many phosphate groups does ATP contain?
Three (Tri)
How is energy released from ATP?
By breaking off a phosphate group.
What does ATP become when 1 phosphate group is removed?
Adenosine Diphosphate (ADP)
What does ATP become when 2 phosphate groups are removed?
Adenosine Monophosphate (AMP)
ATP is replaced via what 3 systems?
- The Phosphagen System
- The Glycolytic System
- The Aerobic System
The Phosphagen System takes a phosphate from ______ to rebuild ATP.
Creatine phosphate (CP)
What is another name for Creatine phosphate (CP)?
Phosphocreatine
Which energy system is the simplest and fastest?
The Phosphagen System
CP is an _____.
Enzyme
How many steps does the Phosphagen System take to replenish ATP?
One step.
The second energy system is the _______ system.
Glycolytic
The Glycolytic System uses a process called ______ to replenish ATP.
Glycolysis
Glycolysis is a ___-step process.
10
Glycolysis splits _____ molecules into ______ and ______.
Glycolysis splits glucose molecules into subcomponents and energy.
The Glycolytic System requires __ ATP to initiate.
2 ATP
One cycle of glycolysis yields __ ATP for a net gain of 2 ATP.
4 ATP
The third energy system is the _____ system.
Aerobic
The aerobic system uses the _______ of glucose left over by glycolysis to release a large amount of ATP.
Subcomponents
These leftover glucose subcomponents are called ____.
pyruvate
The chain of chemical reactions used by the aerobic system to convert pyruvate into ATP is called the ____ ____.
Krebs cycle.
One ‘rotation’ through the Krebs Cycle produces 1 ATP along with several other molecules (NADH and FADH2) which then create even more ATP by going through the _____ ______ chain.
Electron transport
The aerobic system is highly _____.
complex
The aerobic system is relatively slow but produces more than __ times the amount of ATP as glycolysis alone.
10 times the amount
