25 Cards in this Set

  • Front
  • Back
occurs in cytoplasm of the cell
glycolysis
occurs when glucose is available
glycolysis
uses energy stored in glucose to form ATP
glycolysis
glucose is oxidized to pyruvic acid
glycolysis
net gain of 2 molecules ATP
glycolysis
2 NADH carry high energy electrons
glycolysis
occurs in overworked muscles when oxygen is unavailable
fermentation
pyruvic acid from glycolysis is reduced to lactic acid & NADH is oxidized to NAD+ so glycolysis can continue
fermentation
inefficient b/c most of energy in glucose remains in lactic acid
fermentation
pyruvic acid transported into a mitochondrion when oxygen is available
Acetyl Coenzyme A formation
molecule of CO2 is removed from each pyruvic acid
Acetyl Coenzyme A formation
NAD+ removes electrons & H+ to form an acetyl group and NADH
Acetyl Coenzyme A formation
enters Krebs cycle
Acetyl Coenzyme A formation
occurs in matrix of mitochondrion
Krebs cycle
occurs when oxygen is available
Krebs cycle
releases more energy available in molecule of glucose
Krebs cycle
each acetyl coenzyme A that enteres is oxidized to produce 2 CO2
Krebs cycle
2 ATP are produced
Krebs cycle
6 NADH are generated that cary high-energy electrons
Krebs cycle
2 FADH are generated that carry high-energy electrons
Krebs cycle
takes place along inner membrane of mitochondria
electron transport chain
takes place when O2 is available
electron transport chain
completes release of energy that is stored in glucose
electron transport chain
NADH & FADH2 transfer electrons and H+ to electron carriers to make ATP
electron transport chain
O2 accepts low energy electrons & combines w/ H+ to form water
electron transport chain
