Q

waste product of the phosphagen system?

A

no fatiguing waste product

NEED TO KNOW LIMITING FACTOR - this system continually adds P to ADP to form ATP until the levels of CP decrease

16
Q

waste products in the aerobic system?

A

no fatiguing waste product
stage 1 - carbon dioxide
stage 2 - carbon dioxide
stage 3 - water

17
Q

what are the substrates for krebs, glycolysis and ETC?

A

glycolysis - (stage 1) glucose
krebs - (stage 2) acetyl CoA
ETC - (stage 3) hydrogen

18
Q

definition of the phosphagen system?

A

this system involves creatine phosphate and the re-generation of ATP

19
Q

definition of ETC system?

A

provides the body with the highest amount of energy per glucose molecule

20
Q

definition of the krebs cycle?

A

involves the further breakdown of pyruvic acid and the release of more carbon as carbon dioxide

21
Q

definition of glycolysis?

A

involves the splitting of 1 molecule of glucose into 2 molecules of pyruvic acid

22
Q

definition of the lactic acid system?

A

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 cause the muscle to fatigue

23
Q

number of ATP in the phosphagen system and the source of substrate?

A

very limited ATP
the additional phosphate is provided by CP, present in the muscles (and it is removed from this compound by the enzyme creatine kinase) and ADP (from the utilisation of ATP)
