energy system Flashcards
why do we need energy
to sustain life and for the contraction of muscles to produce movement
what are the different energy systems
the ATP-CP (CP stands for creatine phosphate)
the lactic acid system
the aerobic system
what are the two pathways for the production of energy
anaerobic pathway- this does not use oxygen in its chemical reactions
aerobic pathway- requires oxygen in order to produce energy
what does ATP and ADP stand for
adenosine triphosphate
adenosine diphosphate
explain the three sources of chemical compounds that food is broken down into
carbohydrates
they are the primary source of ATP for muscle contraction.
they are broken down into glucose and stored as glycogen in the muscles and the liver
fats
or otherwise known as lipids are the secondary source of ATP for muscle contraction. they are broken down into fatty acids which are stored as fat tissue or are circulated in the blood, and triglycerides which are stored in the muscles
proteins
it is used to produce ATP only under extreme conditions, such as completing in a ultra marathons
how long do each of the energy system last
ATC-CP- up to 10 seconds
lactic acid- 1 or 2 minutes
aerobic system long- long duration
what is ATP
it is the energy released during the breakdown of ATP into adenosine diphosphate (ADP) and the third phosphate that represents the immediate source of energy that can be used by the muscle cell to perform work
