Aerobic Energy Systems

HideShow resource information
Adenosine triphosphate (ATP)
Our energy currency, found in all cells; when broken down releases stored energy.
1 of 21
Resynthesize
To rebuild/ remake/ make again.
2 of 21
Aerobic
with oxygen
3 of 21
Glucose
the main form of carbohydrate found in the body; dissolved in blood plasma; used as an energy source.
4 of 21
Adipose tissue
special tissue made up of cell in which fats are stored; mainly found under the skin and surrounding major organs.
5 of 21
Triglycerides
main form of stored fat, used as an energy source.
6 of 21
Mitochondria
organelle (within the cell) where chemical reactions of aerobic production takes place
7 of 21
Anaerobic
a process that takes place without oxygen
8 of 21
Glycolysis
the process of breaking down glycogen into pyruvic acid, producing some (four molecules) ATP.
9 of 21
Pyruvic acid/ Pyruvate
the end product of glycolysis.
10 of 21
Kerb cycle
a series of chemical reactions in the mitochondria that oxidises acetyl CoA to carbon dioxide and combines hydrogen with hydrogen carriers.
11 of 21
Electron transport chain
series of chemical reactions where hydrogen is oxidised to water and large amounts (34 molecules) of ATP are generated.
12 of 21
Beta-oxidation
breakdown of fats into acetyl CoA within sarcoplasm
13 of 21
Maximal oxygen consumption (VO2 max)
the maximum amount of oxygen taken in, transported and used by the body per minute. Also known as aerobic capacity and measured in millilitres of oxygen, for each kilogram body weight each minutes (ml/kg/min)
14 of 21
Oxygen consumption
the amount of oxygen used by the body.
15 of 21
Oxygen deficit
when insufficient oxygen is available at the start of exercise to provide all the ATP needed aerobically.
16 of 21
Steady state
the period of exercise when oxygen consumption matches the energy being used.
17 of 21
Aerobic capacity
the maximum rate at which a person can consume oxygen.
18 of 21
Excess post-exercise oxygen consumption(EPOC)
the volume of oxygen following exercise/during recovery.
19 of 21
Fast (alactacid, i.e. without lactic acid) component
oxygen used for rapid resynthesize of phosphocreatine and resaturation of myoglobin.
20 of 21
Slow( lactacid, i.e. with lactic acid) component:
oxygen used to remove lactic acid and maintain high heart rate, breathing rate and body temperature.
