|
cellular respiration
|
a metabolic process that uses the energy stored in food to produce ATP
|
|
|
NAD+
|
coenzyme of oxydation-reduction that accepts 2 electron and 1 hydrogen ion to become NADH
|
|
|
FAD
|
coenzyme of REDUX that accepts 2 electrons and 2 hydrogen ions to become FADH₂ which is sometimes used in place of NAD+
|
|
|
Phases of Cellular respiration
|
glycolysis
prep cycle citric acid cycle electron transport and chemiosmosis |
|
|
anaerobic
|
metabolic reaction that does not require oxygen
|
|
|
glycolysis
|
anaerobic breakdown of glucose into two molecules of pyruvate, plus 2ATP and 2NADH
|
|
|
pyruvate
|
end product of glycolysis further reduced into CO₂ and H₂O during respiration or during fermentation as both alcohol and either CO₂ or lactate
|
|
|
substrate level phosphorlyation
|
the process in which an enzyme passes a high-energy phosphate to ADP to form ATP
|
|
|
prep reaction
|
reaction during CR that oxidizies pyruvates with CoenzymeA by releasing CO₂, resulting in acetyl CoA
|
|
|
acetyl CoA
|
the molecule produced during prep reaction made up of 2 carbon acetyl group attached to coenzyme A
|
|
|
citric acid cycle
|
cyclical metabolic reaction within the matrix of the mitochondria that breaks down acetyl groups and produces 4CO₂, 2ATP, 6NADH, and 2FADH₂
|
|
|
cytochrome
|
an iron containing protein that serves as an electron carrier in photo- and CR
|
|
|
oxidative phosphorlyation
|
the production of ATP as a result of energy released from the electron transport chain
