21
Q

ATP

A
  • makes actin slide over myosin
  • enough stored ATP for 1 sec contraction
  • mst rebuild/resynthesize ATP as fast as broken down
  • ENERGY MUST BE OBTAINED FROM RESERVED FUELS IN MUSCLE TO MAKE ADP RECOMBINE W/PHOSPHATE

24
Q

3 ways ATP can be regenerated

A
  • creatine phosphate
  • anaerobic respiration
  • aerobic respiration
25
Q

respiration

A

chemical reactions within a cell that liberate energy

26
Q

cellular respiration

A

cells transferring energy from food to atp

27
Q

hydrolysis

A

ATP is split by hydrolysis

w/addition of water

28
Q

3 immediate energy sources

A

ATP
Creatine phosphate
myokinase

29
Q

in any muscle contraction

A

power or endurance the degradation of atp supplies the chem energy to power musc contraction—all movement big and small

30
Q

energy from food (chem bonds) breakdown is not…

A

directly used by muscle for work…. used to manufacture ATP

31
Q

1 min to move…

A

5 ml in body

32
Q

both contain phosphate groups

A

allowing this system to also be called the phosphagen sstem

33
Q

enzymes creatine-kinase and ATPase…

A

accelerate the speed of the individual reactions

34
Q

PC

A

can only be reformed from Pi+C from energy released in the ATP breakdown, this occurs during rest and recovery

35
Q

PC storage

A

in muscle exceeds ATP–so pc can give energy to ATP

36
Q

primary fuel reserve

A

creatine phosphate

37
Q

w/o this system fast powerful movments could not be performed

A

resynthesis

demand rapid supply rather than a larg amount of ATP energy

38
Q

RApidly available source because of

A
  • does ot depend on long chain of chem reaction
  • does not depend on transporting oxygen to muscles
  • atp+cp are tored w/in the contractile mech
39
Q

lactic acid system/ anaerobic clycolysis

A
  • non oxidative
  • incomplete dissovle
  • 1 foodstuff carbs
40
Q

in th ebody all carbs are converted to

A

simple sugar glucose

41
Q

glucose

A

C6H12O6

  • used immediately- blood sugar
  • stored in the liver and muscle as glycogen
  • porential to be converted and stored as fat
42
Q

glycolisis

A

incompolete breakdown of 1 molecule of glucose o pyruvic acid w/net production of 2 olecules of ATP

43
Q

glycogenolysis

A

breakdown of gylcogen to glucose

44
Q

gluconeogenesis

A

when amino acids are degraded to glucose/glycogen in the liver

45
Q

anerobic glycolysis

A

partial breakdown of glucose in teh absence of oxygen

46
Q

anaerobic glycolysis requires

A

12 seerate and sequential reactions for completion

embden meyerhof cycle

47
Q

lactic acid

A

2C3H6)3

48
Q

tolerate accumulation of lactic acid

A

60-70 g

49
Q

glycolysis produces

A

pyruvic acid anaerobic

50
Q

Pyruvic acid PA

A

w/oxygen acetyl coenzyme A

without oxygen lactic acid

51
Q

glycolitic process

A 
anaerobic glycolysis
glycogen
glucose
ADP+P----ATP
pyruvic acid
insufficient oxygen
lactic acid
fatigue
52
Q

when the amount of LA and H exceed bodys buffering ability and pH deceases the blodd becomes more acidic

A

pain perceived and performance suffers

53
Q

pain lactate burn rhabdomyolysis 6.8

A

hydrogen ions accumulate and stimulate nerve endings located in the muscle

54
Q

drop in performance

A

metabolic fatigue and muscular fatigue

reduce the production of ATP

55
Q

fate of lactate

A
  • converted to pyruvic acid and oxidized to ATP CO2 H2O
  • reconverted to muscle and liver glycogen
  • provides carbons for amino acids wand other proteins
56
Q

lactate removal after exercise

A

removal from the bloodstream is relatively rapid following exercise it does not occur at a constant rate

57
Q

almost 1/2 lactate removed in

A

15-20min no matter what starting level HALF LIFE

near restin glevels reached in 30-60 min

58
Q

lactate removal occurs more quickly during

A

exercise recovery
