Term
|
Definition
| Nicontinamide adenine dinucleotide; coenzyme of oxidation-reduction that accepts electrons and hydrogen ions to become NADH + H+ as oxidations of substrates occurs. During cellular respiration, NADH carries electrons to the electron transport chain in mitochondria |
|
|
Term
|
Definition
| Flavin adenine dinucleotide; a coenzyme of oxidation-reduction that becomes FADH2 as oxidations of substrates occurs, and then delivers electrons to the electron transport chain in mitochondria during cellular respiration |
|
|
Term
|
Definition
| Anaerobic breakdown of glucose that results in a gain of two ATP |
|

Term
|
Definition
Occurs in the matrix of the mitochondria
• Pyruvate altered before entering the Krebs cycle
– Acetyl CoA
• Carbons are completely oxidized to CO2
Krebs Cycle |
|
|
Term
|
Definition
| Also known as Krebs cycle. Cycle of reactions in mitochondria that begins with citric acid; it breaks down an acetyl group as CO2, ATP, NADH, and FADH2, are given off |
|
|
Term
|
Definition
• Electron transport systems are embedded in inner mitochondrial compartment
• NADH and FADH2 give up electrons that they picked up in earlier stages to electron transport system
• Electrons are transported through the system
• The final electron acceptor is oxygen |
|
|
Term
|
Definition
| End product of glycolysis; its further fate, invoking fermentation or entry into a mitochondrion, depends on oxygen availability |
|
|
Term
|
Definition
• Produces 4 ATPs by substrate level phosphorylation
• Costs 2 ATPs to prepare glucose to split into two 3-C fragments |
