energy systems Flashcards
in the aerobic stage how many atp are at each stage?
glycolysis- 2
krebs 2
etc-34
definition on glycolysis
involves the splitting of 1 molecule of glucose into 2 molecules of pyruvate.
definition of Krebs
involves the further breakdown of pyruvate and the release of more carbon as cO2
defintion on etc?
provides the body with the highest amount of energy per glucose molecule.
What are the waste products in the aerobic
( no fatiguing waste product)
stage 1- carbon dioxide
stage 2- carbon dioxide
stage 3- H2O
what are the substrates for Krebs, glycolysis and etc
glycolysis- (stage 1) glucose
krebs- (stage 2)- acetyl coA
etc- (stage 3)- hydrogen
Definition of the phosphagen system
the phosphagen system involves creatine phosphate (cp) and the re-generation of atp
substrates of the phosphagen system
creatine phosphate
number of atp on the phosphagen system
very limited atp,
waste product of the phosphagen system
NEED TO KNOW!- This system continually adds p to add to form atp until the levels of cp decrease.
no fatiguing waste product.
definition of the lactic acid system
Anaerobic glycolysis involves the splitting of 1 molecule of glucose into 2 molecules of pyruvic acid. as no oxygen is present it is converted into lactic acid causing the muscle to fatigue.
substrate of lactic acid
glucose and glycogen
no. of atp in lactic acid
limited (2atp)
waste product in the lactic acid
lactic acid, fatiguing by product.
how many seconds does the phosphagen system last?
8-10 seconds
