ENERGY SYSTEMS Flashcards
where are carbohydrates stored and in what form? and broken down into ?
In the muscle and liver cells in the form of glycogen and broken down to glucose
where can glucose be used in the body ?
can be used by all tissues in the body
how much total energy does carbohydrates provide
50 - 60%
where is fat (i.e. adipose tissue)stored and what is its purpose
not only as a fuel store but also as insulation to prevent heat loss
what is fat composed of and what is it broken down into to release energy
tryglyceride molecules, that are broken down to fatty acids to release energy
what percentage of total energy does fat provide ?
30%
What is protein used as ? and what does it do ?
A building material for the growth and repair of tissues of the body
Protein is not stored in the same way as carbohydrates and fat in the body
unless, give example
there is excess, in which case it will be converted to fat and stored.
What can protein be broken down into to provide energy ? and for what EXPLAIN and give examples
Amino acids
during prolonged endurance events e.g long distance swimming or cycling
how much total energy does protein provide ?
around 10 - 15%
What are the three energy systems called ?
Phosphocreatin system
lactic acid system
aerobic system
How many ways can ATP (Adenosine tripsophate be resynthesised ? and what are they referred to as ?
three
The Energy Systems
How can energy be released in the body and what does it produce ?
by the breakdown of fat, carbohydrate and protein to produce ATP
what are the phosphocreatin system and lactic acid system termed as ?
anaerobic
what system does not use oxegen ? and what is produced there very quickly ?
the P C and lactic acid systems i.e. anaerobic
A T P
