fermentation
|
anaerobic, without O2, makes a limited amout of ATP from glucose without an electron transport chain, produces lactic acid or alcohol
|
|
cellular respiration
|
most efficient way to make ATP, O2 is consumed as a reactant
|
|
phosphorylation
|
The creation of a phosphate derivative of an organic molecule. This is usually achieved by transferring a phosphate group from ATP.
|
|
oxidative phosphorylation
|
the production of ATP using energy derived from the redox reactions of the electron transport chain
|
|
substrate-level phosphorylation
|
the formation of ATP by directly transferring a phosphate group to ADP from an intermediate substrate in catabolism
|
|
oxidation
|
the loss of elextrons from a substance involved in a redox reaction
|
|
reduction
|
the gaining of electrons by a substance involved in a redox reaction
|
|
coenzyme
|
an organic nonprotein molecule serving as a cofactor.
|
|
dinucleotide
|

|
|
nicotinamide adenine dinucleotide(NAD+)
|
a coenzyme presnet in all cells that helps enzymes transfer electrons during the redox reactions of metabolism
|
|
flavin adenine dinucleotide (FAD)
|

|
|
dehydrogenase
|
an enzyme that oxidizes a substrate by transferring one or more protons and a pair of electrons to an acceptor
|
|
mitochondrion
|
an organelle in eukaryotic cells that serves as the site of cellular respiration
|
|
matrix
|
important in the production of ATP with the aid of the ATP synthase contained in the inner membrane, space enclosed by the inner membrane
|
|
cristae
|
an infolding of the inner membrane of a mitochondrion that houses the electron transport chain and the enzyme catayzing the synthesis of ATP
|
|
intermembrane space
|

|
|
Sir Hans Krebs
|
responsible for describing the citric acid cycle
|
|
electron carrier
|

|
|
cytochrome
|
an iron containing protein, a component of electron transport chains in mitochondria and cholorplasts
|
|
heme group
|
prosthetic that has four organic rings surrounded by an iron atom
|
|
electron transport chain
|
a group of molecules in the inner membrane that synthesize ATP by means of an exergonic slide of electrons
|
|
ubiquinone
|
lipid electron carrier, only member of the electron transport chain that is not a protein
|
