energy systems and nutrients Flashcards
for movement to occur what must the body do
transfer stored chemical energy to mechanical energy
atp is bound together by
high energy bond
what do we need to do in order to get energy
break down the bond between the second and third phosphate molecules
the breakdown leaves us with 2 compounds …. adenosine di phosphate and a loose phosphate molecule
in order to resensythize atp what do we need to do
reattach the adp and the phosphate again so that the atp can be broken down
what are the energy systems
atp-pc systems… anaerobic
lactic acid system….anaerobic
aerobic energy system
in the use of energy systems if the workout is short with high intensity what type of energy system do we use
atp–pc system
longer workout with high intensity what system do we use
lactic acid system
longer exercise and submaximal pace what energy system do we use
aerobic system
what is the most inefficient energy system
atp| pcr system
what part of the body is atp stored for quick access
muscle and the liver
what is atp broken down to in order to generate energy for the body
ADP PLUS P
ADVANTAGES OF THE PC SYSTEM
can be generated quickly
no fatiguing by products
creatine suplimentation extends the time that the atp pcsystem can be utilized
when is the lactic acid system used
when the oxygen supply is inadequte
when pc runs out the body uses glycogen
lasts 10-60 secs
lactic acid breaks down glycogen to form atp through a process called what
anaerobic glycolysis or glycolysis
one molecule of glucose from the blood and 1 molecule of glycogen will produce how many atps respectively
2 atp
3 atp
what makes the muscle feel very weak and heavy
lactic acid build up
which is the most efficient and slowest energy system
aerobic
in aerobic system if oxygen is present the pyruvic acid is converted into what
34 molecules of atp
what is the waste product of the aerobic system
carbon dioxide and water
aerobic system provides the body with what
prolonged and steady supply of energy
how many amount of atp does each system produce
atp\pcr ….. 1 mole
glycolytic system …2 moles
oxidative system …38 moles
state where lactate contributes to glucose production in known as
gluconeogenesis
what is lactate threshold
first accumulation of blood lactate above resting conc
what marks the point where the body starts using carbohydrate as a primary fuel and stops using fat as its primary fuel
lactate threshold
