energy systems

Question 1

ATP-PC (Alactic) system

Answer 1

-atp stores in the muscle last approx 3 secs
-when atp stores have been used they form adp
-we use creatine phosphate (pcr) which is also stored in muscles
-when creatine phosphate bond breaks the released phosphate binds with adp to form atp

Question 2

is the ATP PC system aerobic or anaerobic?

Answer 2

anaerobic

Question 3

what is the energy source of the ATP PC system?

Answer 3

creatine phosphate

Question 4

what’s the recovery time of the ATP PC system?

Answer 4

1:10

Question 5

sporting example for the ATP PC system

Answer 5

100m, shot put, high jump

Question 6

lactate system

Answer 6

-breaks down glycogen without the use of oxygen this is called anaerobic glycolysis
-when we break down a molecule of glycogen it produces 2 molecules of ATP
-also produces pyruvate acid that is converted to the lactic acid
-lactic acid is a waste product
-takes 8mins to recover from lactate system
-in this time lactic acid is removed and glycogen stores replaced

Question 7

what is the energy source for the lactate system?

Answer 7

glucose, glycogen

Question 7

is the lactate system aerobic or anerobic?

Answer 7

anaerobic

Question 8

how long does the lactate system last?

Answer 8

1-2 mins

Question 9

sporting examples for the lactate system?

Answer 9

400m, downhill skiing, 200m swim

Question 10

aerobic system stage 1 (anaerobic glycolysis)

Answer 10

-glycogen is broken down through the process of aerobic glycolysis
-this produces 2ATP and pyruvic acid

Question 11

aerobic system stage 2 (krebs cycle)

Answer 11

-pyruvic acid enters krebs cycle
-then converted to citric acid
-broken down with the use of oxygen and produces 2 ATP
-carbon dioxide and hydrogen are released

Question 12

aerobic system stage 3 (electron transport chain)

Answer 12

-hydrogen enters the electron transport chain
-links with a hydrogen acceptor
-hydrogen forms with oxygen to produce 34 ATP
-water is produced

Question 13

how many ATP does this aerobic system produce?

Answer 13

38 ATP

Question 14

what are the energy sources of the aerobic system?

Answer 14

glucose, glycogen, fatty acids

Question 15

how long does the aerobic system last?

Answer 15

unlimited

Question 16

recovery time of the aerobic system?

Answer 16

few hours, up to 2-3 days

Question 17

sporting examples of the aerobic system?

Answer 17

marathon, triathlon

Question 18

adaptions- increase in creatine stores

Answer 18

more creatine means that you can exercise the ATP-PC energy system for longer high intense

Question 19

adaptions-increase tolerance to lactic acid

Answer 19

-lactic acid is a waste product from the lactate system
-lactic acid makes the muscles feel fatigued
-a tolerance to lactic acid will allow the muscles to work for longer without getting fatigued

Question 20

adaptions-improved aerobic energy system

Answer 20

adaptions to cvs and respiratory system will improve the aerobic energy system as it will allow increased oxygen delivery to the working muscles

Question 21

adaptions-to use fat as a energy source

Answer 21

training increases the ability to use fats as a energy source this helps the aerobic system

Question 22

adaptions-increase in glycogen stores

Answer 22

this will benefit both the lactic and aerobic system and it provides extra fuel

Question 23

adaptions-increase in mitochondria

Answer 23

aerobic respiration happens inside the mitochondria, the more mitochondria the more oxygen can be used for an energy source

Question 24

what's diabetes?

Answer 24

the body inability to regulate the amount of glucose in the blood due to the lack of insulin function- aerobic exercise can help the body use insulin more effectively

Question 25

type 1 diabetes?

Answer 25

body is unable to produce insulin as body cannot use glucose for energy it looks else where such as fats and proteins

Question 26

type 2 diabetes

Answer 26

developed when not enough insulin is produced by the body

Question 27

lactate system and children

Answer 27

-lack of muscle mass, lower glycogen stores, fewer essential enzymes for energy production
