breaking down something
gets energy from it
anabolism
building something
uses energy
aerobic respiration 3 steps
glycolysis
citric acid cycle
electron transport chain
in glycolysis, what does glucose turn into?
pyruvate
electrons carried via what in glycolysis?
NADH
electrons carried via what in citric acid cycle
NADH and FADH2
how is ATP produced in glycolysis and citric acid cycle?
substrate level phosphorylation
how is ATP produced in ETC
oxidative phosphorylation
final electron acceptor of aerobic respiration

myoglobin
protein that carries oxygen to muscle tissue
contains red pigment
what muscles have a higher concentration of myoglobin?
those used more frequently
why does light meat and dark meat differ in color?
different concentrations based on the muscle’s use
