ch 10 Flashcards
mitochondria
function of mitochondria
produce energy from glucose, fats, proteins
structure of mitochondria
outer membrane
inner membrane
intermembrane space
matrix
function of outer membrane
keep cytosol separate from mitochondria
contains channels that nutrients and ATP cross
inner membrane function
holds ETC
has channels
intermembrane space function
hydrogen ions get concentrated
H+ movement powers ATP production
matrix function
citric acid cycle occurs here
what pulls mitochondria together/apart
proteins
catabolism
break down molecules to get energy
metabolism
sum of chemical reactions in the body
anabolism
building up molecules from smaller ones
three main steps of glucose catabolism
- glycolysis
- citric acid cycle
- oxidative phosphorylation
goals of glucose catabolism
produce ATP
produce NADH and FADH2
electron carriers
molecules remove electrons from other molecules
gylcolysis
glucose is converted into TWO pyruvate molecules
also produces TWO ATP and TWO NADH molecules
occurs in cytosol
each step of glycolysis is catalyzed by
an enzyme
