Intro Flashcards
(25 cards)
glycemic index
how fast carbs are absorbed to affect blood glucose
glycogen
stored glucose
glucose
hallmark of sports nutr
glycogenolysis
breakdown of glycogen
glycogenesis
make glycogen from glucose
gluconeogenesis
glucose from non-CHO sources such as glu-alanine cycle or cori cycle
glycolysis
breaking down glucose into pyruvates
catabolic
break down
anabolic
build up
lipolysis
breakdown of triglycerides= fatty acids +glycerol
lipogenesis
fatty acids+ glycerol= triglycerides
proteolysis
breakdown of protein into amino acids
protein synthesis
amino acids form protein
what does RER stand for?
respiratory exchange ratio
RER=
VCO2 (Produced)/ VO2 (consumed)
used to relate the intensity of exercise and overall conditioning
fats
0.70 a big energy source using krebs/CAC, aerobic exercise
carbs
1.02 VCO2 higher than VO2, anaerobic uses glycolysis (mostly fast)
oxidoreductases
oxidation-reduction, donating or accepting an electron
transferase
transfer one aspect of a molecule to another molecule with same outcome
hydrolase
triggers hydrolysis or a chemical bond; breaks a chemical bond by the addition of water
lyases
triggers the breaking of bonds by means other than hydrolysis and oxidation; the reverse is also possible, causes different outcome
isomerases
allow for simple rearrangement within a molecule
most immediate source of energy
ATP
second most immediate form of energy
creatine
