Glycolysis
decomposition of glucose to pyruvate
Glycolysis
2 ATP are added, 2 NADH are produced
Glycolysis
4 ATP produced, 2 pyruvate are formed
Krebs Cycle
Pyruvate to accetly CoA
Krebs Cycle
3 NADH, 1 FADH
Krebs Cycle
1 ATP, CO2
Oxidative Phosphorylation
the process of extracting ATP from NADH and FADH2.
Oxidative Phosphorylation
Electrons from NADH and FADH2 pass along an electron transport chain
Oxygen
The final electron acceptor of the electron transport chain, the .5 O2 accepts the electron and together with H2 forms water
Mitochondria
where two major processes of aerobic respiration, the Krebs cycle and oxidative phosphorylation occurs
Outer membrane
consist of a double layer of phospholipids
Intermembrane space
this is the narrow area between the inner and outer membranes. H+ ions accumulate here
Inner membrane
oxidative phosphorylation occurs here
ATP synthase
phosphorylation of ADP to form ATP in oxidative phosphorylation
Matrix
fluid material the fills the are inside the inner membrane
Chemiosmosis
the mechanism of ATP generation that occurs when enegy is stored in the form of a proton concentration gradient across a membrane
Substrate level phosphorylation
when a phosphate group and its associated energy is transfered to ADP to form ATP with a phosphate group
Oxidative phosphorylation
when a phosphate group and its associated energy is transfered to ADP to form ATP without a phosphate group
Anaerobic Respiration
NADH accumulates, Krebs Cycle and glycolysis both stop
Alcohol fermentation
Pyruvate to acetaldehyde to Ethanol, 1 CO2 produced, 1 NAD+ released
Lactic Acid Fermentation
pyruvate to lactate; NADH gives up its electrons to form NAD+
