Q

describe a coupled reaction

A

products from one reaction are used in another

  1. creatine kinase released, PC is broken down (PC -> P + C + energy)
  2. energy and phosphate binds with ADP left in the cell and produce ATP (energy + ADP + P -> ATP)
  3. ATP is used for high intensity exercise

A
  • increase in ATP and PC stores

Q

describe what happens during anaerobic glycolysis

A
  1. glycogen from liver stores is broken down into glucose by GPP (glycogen phosphorolase)
  2. glucose is then broken down into pyruvic acid by PFK (phosphofructokinase)
  3. this makes 2 ATP in the process
  4. pyruvic acid is then broken down into lacic acid by LDH (lactate dehydrogenase)

Q

what are the strengths of the glycolytic system

A
  • no delay for O2 as large fuel store’s in the liver, muscle and bloodstreams
  • relatively fast fuel breakdown for ATP resynthesis
  • produces energy for high intensity activities
  • lactic acid can be recycled into fuel for further energy production

Q

what are the characteristics of the aerobic energy system

A
  • uses oxygen as it’s aerobic
  • low intesnsity activities
  • longer duration
  • activities lasting 3+ minutes
17
Q

dedscribe what happens in the aerobic energy system

A

STAGE 1: AEROBIC GLYCOLYSIS
1. glucose is broken down into pyruvic acid
2. pyruvic acid goes through a link reaction catalysed by CoA which produces Acetyl CoA

STAGE 2: KREB CYCLE
3. oxaolacetic acid binds with Acetyl CoA to produce citric acid, this is oxidised through reactions
4. hydrogen and CO2 is released, energy synthesise 2ATP

STAGE 3: ELECTRON TRANSPORT CHAIN
5. H ions are carried down ETC, along cristae b y NAD and FAD, splitting into ions and electrons
6. ions are oxidised and removed as H2O
7. electrons are carried by NADH and FADH, resynthesise 34 ATP

18
Q

what are the strengths of the aerobic system

A
  • large fuel stores, triglycerides, FFA’s, glycogen and glucose
  • high ATP yeild and long duration of energy production
  • no fatiguing by-products
19
Q

what are the weaknesses of the aerobic system

A
  • delay for oxygen delivery and complex series of rections
  • slow energy production limits activity to sub-maximal activity
  • triglycerides and FFA’s demand for 15% more oxygen for breakdown
20
Q

what are FFA’s

A

free fatty acids
they’re an alternative energy store to glucose
FFA’s converted into acetyl CoA then follow the Kreb cycle
produce a higher yeild of ATP

21
Q

what’s an energy continuum

A

relative contribution of each energy system depending on intensity and duration

22
Q

what other factors effect which energy system is used

A
  • playing position
  • level of competition: hard match with tough competition is more likely to be higher intensity, using anaerobic systems, than lower level competitions
  • tactics and strategies: man-man marking is higher intensity than zonal marking
  • structure of the game: large pitch would be more aerobic than games on smaller courts
