explores how the human body responds to physical activity and sports performance.
1 of 22
carbohydrates, lipids, protein
you need fuel for exercise - chemical energy (endogenous) - you can find energy from carbohydrates (liver, muscle,fat.protein)
2 of 22
exogenous process (chemical energy)
muscle storeds more fat for energy than the liver does for glucose
3 of 22
endergonic process (chemical energy)
requires energy
4 of 22
gluconeogenesis
is the body process of making new sugar which occurs in the liver due to amino acids, glycerol, pyruvate and lactate
5 of 22
metabolism
the sum of all the energy processes in the body, the production of energy for essential process, to synthesis new organic material.
6 of 22
homeostatsis
the constant internal environment in the cell
7 of 22
bioenergetic
how we get energy
8 of 22
anabolic processess
the build up or construction of molecules from smaller units; generally requires energy
9 of 22
catabolic processess
the breakdown of molecules into smaller units, which are then oxidised to release energy
10 of 22
oxidized
breaking down of energy and using it
11 of 22
energy transfer
the first law of thermodynamics energy can't be created or destroyed but changes from one form to another. energy transfer will always occur in one direction
12 of 22
exercise metabolism
metabolism involves all of the chemical reactions of the body biomolecule that helps synthesis and breakdown
13 of 22
energy currency
ATP, cellular respiration and metabolic pathways
14 of 22
phosphorylation
the transfer of energy in the form of phosphate bonds, vital for cell regulation, the energy is generated by the oxidation of carbs, fats and proteins
15 of 22
cellular oxidation - oxidation
transfer of O2 H+ or electrons, always loss of electrons, increase in oxidative state
16 of 22
cellular oxidation - reduction
gain of electrons, reduction of oxidative state
17 of 22
short term - alactic pathway
ATP-PC pathways (galactic pathways) - no oxygen is needed, energy is supplied quickly - no lactic acid is produced
18 of 22
short term - lactic pathway
anaerobic glycolysis - glucose and glycogen = quick energy, more ATP is produced and no oxygen is used which creates lactic acid.
19 of 22
long term - aerobic system
Krebs cycle, larger amounts of ATP produced by fats and carbs, uses oxygen which the supply takes longer, more efficient, recovery.
20 of 22
relative contribution - energy supply
fules will contribute to meeting energy demands - energy demands relative to requirements of sporting events
21 of 22
relative contribution - fitness
specific training will influence both energy demand and contribution from pathways.
