Test one Flashcards
Oxidative phosphorylation (sub groups)
krebs cycle, Electron transport chain
Substrate phosphorylation (sub groups)
Phosphagen system, glycolysis
Oxidative phosphorylation is happening where?
Mitochondria
Substrate phosphorylation is happening where?
Sarcoplasm
Phosphagen system is composed of what two reactions?
Creatine kinase, Adenylate kinase,
Adenylate kinase reaction?
ADP+ADP—-> ATP+AMP AMP produces ammonia
Creatine kinase reaction?
ADP+PCr—> ATP+Cr
Phosphorylation
re-synthesis of ATP from ADP
Dephosphorylation
Breaking of phosphate ATP —> ADP Releases energy
Fats…… * Break down to Lipids is? lipolysis *
Lipids—> beta oxidation—> Acetyl CoA—> Krebs Cycle—> ETC
Proteins
Amino Acids—> Deamination (pyruvate—> Acetyl CoA) (Acetyl CoA) (Krebs Cycle) —> ETC
Carbohydrates
Glucose—-> Glycolysis—>pyruvate—> krebs cycle—> ETC
Time limit for phosphagen system
1-7 seconds
Time limit for glycolysis
10 seconds - 2min
Time limit oxidative system
maximal work lasting more than 2 min and all sub-maximal work
NAD and FAD (Krebs)
are reduced through the krebs cycle by gaining electrons
3 NADH and 1 FADH2 (ETC)
are oxidized through the ETC by removing the hydrogens
What is the final phase of the ETC?
hydrogen synthesizing with oxygen producing water.
What happens to ATP, ADP, and PCr levels during both light exercise?
ATP neutral , ADP increases, PCr neutral
What happens to ATP, ADP, and PCr levels during very high intensity exercise?
ATP decreases, ADP Increases, and PCr decreases
ATP at rest ?
25 mmol/kg
PCr at rest?
75 mmol/kg
What happens to ATP and PCr levels during wing gate cycle test?
50 percent drop in ATP.
90 percent drop in PCr.
Creatine monohydrate for performance
Increases sarcomere (muscle size), increases ATP synthesis in the PCr system, increase strength and power.
Creatine monohydrate increases?
increases the amout of PCr in the body allowing for longer ATP-PCr production increase outputs of very high intensity.
loading phase for creatine monohydrate
6 days, 20 grams a day, 4 times a day at 5 grams per intake. then 5 grams a day for 28 days. The other option is 5 grams a day for a month.
What is the impact of creatine monohydrate on both PCr stores and free creatine in the body?
There is an increase of PCr stores because there is more free creatine available in the body.
What percent increase in creatine phosphate stores when creatine is take?
10-40 percent
