|
Aerobic Respiration |
Complete oxidation of glucose to CO2 in the presence of O2 producing ATP. |
|
|
Glycolysis |
"Breaking sugar" a six-carbon glucose molecule splits into two three-carbon pyruvate molecules. |
|
|
Pyruvate |
The three-carbon product of glycolysis. |
|
|
NADH |
Electron carrier molecule. |
|
|
Krebs Cycle |
Oxidize the pyruvate and release CO2. |
|
|
Electron transport chain |
Transfers energy rich electrons from NADH to FADH2 through a series of membrane proteins. |
|
|
ATP synthase |
An enzyme forms a channel in the membrane, releasing the protons and using their potential energy to add phosphate to ADP. |
|
|
Mitochondria |
Houses the other reactions of cellular respiration. |
|
|
Cristae |
Folds of the inner membrane of the mitochondria. |
|
|
Intermembrane compartment |
The area between the two membranes in the mitochondria. |
|
|
Mitochondrial matrix |
Is the space enclosed within the inner membrane |
|
|
Substrate level phosphorylation |
An enzyme transfers a phosphate group directly from a high-energy "donor" molecule to ADP |
|
|
Acetyl coenzyme A |
The compound that enters the Krebs cycle |
|
|
Chemiosmotic phosphorylation |
Protons move down their gradient through ATP synthase back into the Matrix and ADP is phosphorylated to ATP |
|
|
Anaerobic respiration |
An inorganic molecule other than O2 is the electron acceptor at the end of the electron transport chain |
|
|
Fermentation |
Electrons from NADH reduce pyruvate. |
|
|
Alcoholic fermentation |
Pyruvate is converted to CO2 and ethanol while NADH is oxidized to produce NAD+ |
|
|
Lactic acid fermentation |
A cell uses NADH to reduce pyruvate but in this case the products are NAD+ and lactic acid or its close relative, lactate. |
