Energy Systems Simplified

These flashcards cover the key concepts and details related to energy systems in the body, focusing on ATP, anaerobic and aerobic systems, and their metabolic processes.

ATP stands for __ and is the only usable form of chemical energy in the body.

Adenosine Triphosphate

The ATP-PC system works __ (without the presence of oxygen).

anaerobically

The breakdown of one mole of glucose is coupled to the resynthesis of __ moles of ATP.

two

In the Lactic Acid System, after stores of phosphocreatine are depleted, ATP must be resynthesized using __.

glucose

A typical Lactic Acid System activity is the __ or any activity lasting 30-60 seconds.

400m race

The complete oxidation of glucose can produce up to __ molecules of ATP.

38

The cycle involves acetyl coenzyme A combining with oxaloacetic acid.

Krebs

During anaerobic glycolysis, energy is released to allow ATP _ by producing two molecules of ATP.

resynthesis

For every molecule of phosphocreatine broken down, there is enough energy released to create __ molecule of ATP.

one

The aerobic system is used when exercising at __ intensity and oxygen is readily available.
