energy Flashcards
what is energy
it’s what our body uses to perform specific function
what does specific function energy do for our body are
breathing sleeping, digesting, studying and playing sport (everything u do requires energy)
Adenosine Triphosphate (ATP)
is a energy source that provides energy to the working muscles. (ATP provides all the energy required for muscular effort)
Where is energy produced
in the muscle fibres (anaerobic) and in the mitochondria (aerobic)
where is ATP stored
its stored in limited quantities in the muscles,
where does energy come from when u need to create more
muscle fibres producing ATP from food fuels
what foods do ATP produce from
Creatine Phosphate (CP), Carbohydrates, Fats, Proteins
What is Creatine Phosphate used for
maximal energy demands
where is creatine phosphate stored in the body
50% of creatine is stored in muscle, and other 50% made from amino acids.
Carbohydrates are stored in the body as
glycogen
glycogen provides the energy from ATP under what conditions
both anaerobic and aerobic conditions.
what is the main source of energy production for the body
carbohydrates
fats contribute to ATP production to meet what demands
sub maximal energy demands
ATP is produced from protein only when
its extreme circumstances for ATP produce
our mechanical energy for muscular contraction requires …
the chemical breakdown of the ATP molecule.
the energy for contraction comes from the ..
bond or the “tail” of the phosphate molecule.
our ATP stores are very limited therefore
ADP must continually be rebuilt to ATP
nutrients assist in the ATP cycle by..
providing energy to rejoin the floating phosphate back to the ADP to make ATP once again
what are the 4 factors ATP is used during the physical activity
-activity duration
-activity intensity
-the individuals aerobic fitness level
-the level of recovery achievable between efforts
when the body participates in physical activity it can produce energy either
anaerobic -without oxygen
or aerobically - with oxygen
what do the 3 energy systems produce
energy
Name the 3 energy systems
-phosphate energy system (ATP-PC)
-Anaerobic glycolysis system
-aerobic glycolysis system
