Sarcoplasm

Question 5

Phosphagen system is composed of what two reactions?

Answer 5

Creatine kinase, Adenylate kinase,

Question 6

Adenylate kinase reaction?

Answer 6

ADP+ADP—-> ATP+AMP AMP produces ammonia

Question 7

Creatine kinase reaction?

Answer 7

ADP+PCr—> ATP+Cr

Question 8

Phosphorylation

Answer 8

re-synthesis of ATP from ADP

Question 9

Dephosphorylation

Answer 9

Breaking of phosphate ATP —> ADP Releases energy

Question 10

Fats…… * Break down to Lipids is? lipolysis *

Answer 10

Lipids—> beta oxidation—> Acetyl CoA—> Krebs Cycle—> ETC

Question 11

Proteins

Answer 11

Amino Acids—> Deamination (pyruvate—> Acetyl CoA) (Acetyl CoA) (Krebs Cycle) —> ETC

Question 12

Carbohydrates

Answer 12

Glucose—-> Glycolysis—>pyruvate—> krebs cycle—> ETC

Question 13

Time limit for phosphagen system

Answer 13

1-7 seconds

Question 14

Time limit for glycolysis

Answer 14

10 seconds - 2min

Question 15

Time limit oxidative system

Answer 15

maximal work lasting more than 2 min and all sub-maximal work

Question 16

NAD and FAD (Krebs)

Answer 16

are reduced through the krebs cycle by gaining electrons

Question 17

3 NADH and 1 FADH2 (ETC)

Answer 17

are oxidized through the ETC by removing the hydrogens

Question 18

What is the final phase of the ETC?

Answer 18

hydrogen synthesizing with oxygen producing water.

Question 19

What happens to ATP, ADP, and PCr levels during both light exercise?

Answer 19

ATP neutral , ADP increases, PCr neutral

Question 20

What happens to ATP, ADP, and PCr levels during very high intensity exercise?

Answer 20

ATP decreases, ADP Increases, and PCr decreases

Question 21

ATP at rest ?

Answer 21

25 mmol/kg

Question 22

PCr at rest?

Answer 22

75 mmol/kg

Question 23

What happens to ATP and PCr levels during wing gate cycle test?

Answer 23

50 percent drop in ATP.

90 percent drop in PCr.

Question 24

Creatine monohydrate for performance

Answer 24

Increases sarcomere (muscle size), increases ATP synthesis in the PCr system, increase strength and power.

Question 25

Creatine monohydrate increases?

Answer 25

increases the amout of PCr in the body allowing for longer ATP-PCr production increase outputs of very high intensity.

Question 26

loading phase for creatine monohydrate

Answer 26

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.

Question 27

What is the impact of creatine monohydrate on both PCr stores and free creatine in the body?

Answer 27

There is an increase of PCr stores because there is more free creatine available in the body.

Question 28

What percent increase in creatine phosphate stores when creatine is take?

Answer 28

10-40 percent
