Q

whats the equation to convert ATP to ADP and what enzyme is needed and what type of reaction is this?

A

ATP —–> ADP+Pi + energy
ATPase breaks the bond
its an exothermic reaction (releases energy)

Q

what intensity is the lactic acid system?

A

high-medium

19
Q

how long does the lactic acid system last for?

A

lasts 11-180 seconds

20
Q

where does the reaction in the lactic acid system take place?

A

the muscle sarcoplasm

21
Q

whats the ATP yield of the lactic acid system?

A

2

22
Q

lactic acid system process to resynthesis ATP

A

glycolysis:
glycogen to glucose (GPP enzyme) to pyrouvic acid (PFK enzyme) to lactic acid (LDH enzyme)
this breaks down glucose to provide energy via coupled reactions to resynthesis ADP back to ATP.

23
Q

what are all the enzymes needed in the lactic acid system?

A

GPP- glucogen phosphorylase
PFK- phosphofructokinase
LDH- lactose dehydrogenase

24
Q

whats the intensity of the aerobic system?

A

low

25
Q

how long does the aerobic system last?

A

more than 3 minutes

26
Q

what fuels the aerobic system?

A

free fatty acids

27
Q

what’s the ATP yield of the aerobic system?

A

38

28
Q

whats the process of the aerobic energy system?

A

stage 1: glycolysis
glycogen to glucose (GPP enzyme) to pyrouvic acid (PFK) enzyme

stage 2: kreb cycle/ citric acid system

stage 3: electron transport chain

29
Q

where does glycolysis occur?

A

in the muscle sarcoplasm

30
Q

how many ATP does glycolysis produce?

A

2

31
Q

whats the kreb cycle/ citric acid system?

A

pyrouvic acid goes to acetyl CoA
this goes to oxaloacetic acid
this goes to citric acid which goes back to acetyl CoA

free fatty acids and oxygen goes in
H+ and carbon dioxide out

32
Q

where does the kreb cycle/ citric acid cycle occur?

A

matrix of mitochondria

33
Q

how many ATP does the kreb cycle produce?

A

2

34
Q

what happens in the electron transport chain?

A

H+ is carried by the hydrogen carriers NAD and FAD
with oxygen they produce water

35
Q

where does the electron transport chain happen?

A

the cristae of the mitochondria

36
Q

how many ATP does the electron transport chain produce?

A

34

37
Q

advantages of ATP-PC system

A

high intensity
no transportation needed
no waste products
already stored naturally

38
Q

disadvantages of the ATP-PC system

A

only lasts 3-10 seconds
only 1ATP produced

39
Q

advantages of the lactic acid system

A

produces more ATP (2) and longer duration (11-180s) then ATP-PC system
can be regenerated
glycogen stored in the liver
no transportation needed

40
Q

disadvantages of the lactic acid system

A

waste product lactic acid
only 2 ATP compared to 38 in aerobic system
only lasts 180 seconds

41
Q

advantages of the aerobic system

A

long duration, over 3 mins
produces 38 ATP
no harmful bi products

42
Q

disadvantages of the lactic acid system

A

low intensity
has to be transported
lots of processes, takes time
reliant on oxygen

43
Q

what does the energy continuum allow us to know?

A

the predominant energy system for the activity so we can inform our training (train this energy system)

44
Q

at rest, which energy system do we use mostly?

A

aerobic system as there’s a plentiful supply of oxygen for resynthesis of ATP
