Energy Keywords
Flashcards do conjunto (28)
- 1Chemical energyEnery stored within the bonds of chemical compounds (within molecules)
- 2Adenosine TriPhospahte ATPChemical energy stored as a high energy compound in the body. It is the only immediately usable source of energy in the human body
- 3Potential Energy'Stored' energy which is ready to be used when required
- 4Kinetic energyEnergy in the form of muslce contractio/joint movement
- 5ForceA pull or push that alter, or tends to alter, the state of motion of a body. It is measured in Newtons (N)
- 6CompoundA mixture of elements
- 7EnzymesProtein molecules that act as catalysts for the body's chemical reactions. The enzyme name typically ends with the suffix -ase
- 8ATPaseThe enzyme that helps break down ATP to release energy
- 9ExothermicA chemical reaction that releases energy as it progresses
- 10EndothermicA chemical reaction that requires energy to be added for it to progress
- 11Coupled reactionWhen the products from one reaction, such as energy, are then used in another reaction
- 12AnaerobicA reaction that can occur without the presence of oxygen
- 13SarcoplasmFluid-like gelaine that fills the spaces within the muscle cells and is a store of glcogen, fat, proteins, enzymes and myoglobin
- 14ThresholdThe point when one energy system stops being the predominant energy provider for the resynthesis of ATP
- 15Anaerobic glycolysisThe partial incomplete breakdown of glucose into pyruvic acid
- 16Lactate/Lactic acidAnaerobic glycolsis produces lactic acid, but it is quickly converted into a substrate salt called lactate which is easier to disperse via the blood stream. Although different compounds, the terms 'lactate' and 'lactic acid' are often used interchangeably
- 17MatrixIntracellular fluid within the mitochondra where oxidation takes place
- 18MitochondriaSmall sub-unit (membrane) sites of a muscle cell where aerobic respiration takes place
- 19CristaeInternal membrane/compartments/fold-like structures within mitochondria
- 20VO2 MaxMaximum oxygen consumption attainable during maximal work
- 21Excess post-exercise oxygen consumption EPOCThe excess oxygen consumption, above that at a resting level, during recovery, to restore the body to its pre-exercise state
- 22AlactacidThe 'a' before lactacid signifies it is without lactic acid
- 23MyoglobinRed pigment in muscles that stores oxygen before passing it on to mitochondria for aerobic respiration
- 24VO2Volume of oxygen consumed
- 25Carbonic Acid H2CO3Carbon dioxide combined with water
- 26Carbaminohaemoglobin HbCO2Carbon dioxide combined with haemoglobin
- 27Interval trainingA form of training incorporating periods of work interspersed with periods of recovery
- 28VO2 maxMaximum volume of oxygen that can be consumed during maximal work
