Question Answer
Location of the citric acid cycle mitochondria
Main oxidative function of the citric acid cycleoxidation of acetyl-CoA to CO2 and H2O
Location of the pyruvate dehydrogenase complexmitochondrial matrix
Enzymes that compose the pyruvate dehydrogenase complexpyruvate dehydrogenase, dihydropropyl transacetylase, dihydrolipoyl dehydrogenase, pyruvate dehydrogenase kinase, pyruvate dehydrogenase phosphatase
This molecule is important catalyzing the acetyl group transfer to form acetyl-CoA from CoA-SH Dihydropropyl transacetylase
This molecule is important in the facilitation of acetyl-CoA formationlipoic acid
This coenzyme is important in the reoxidation of lipoic acid FAD
This coenzyme is important in the reoxidation of FADNAD+
Fatty acid oxidation (aka B-oxidation) occurs hereintermembrane space of mitochondria
This molecule is important in the transport of fatty acid acyl-CoA across the inner membranecarnitine
These 4 methods can be used to synthesize acetyl-CoAB-oxidation, amino acid catabolism, ketones, alcohol
The rate-limiting enzyme of the citric acid cycleisocitrate dehydrogenase
Which enzyme in the citric acid cycle will catalyze the phosphate transfer from GTP to create the only ATP in the citric acid cyclenucleosidediphosphate kinase
The only step in the citric acid cycle that doesn't take place in the mitochodrial matrix but instead in the inner membranefumarate formation
Molecule starts the citric acid cycleoxaloacetate
Net NADH production from the citric acid cycle3 NADH
Important substrates for the citric acid cyclepyruvate, citrate, isocitrate, a-ketoglutarate, succinyl-CoA, succinate, fumarate, malate, oxaloacetate
Amount of total ATP produced from the citric acid cycle per glucose25 ATP
Net ATP produced from glycolysis through oxidative phosphorlyation30-32 ATP
Main checkpoints of the citric acid cyclecitrate synthase, isocitrate dehydrogenase, a-ketoglutarate dehydrogenase complex
The transfer of electrons from NADH to coenzyme Q occurs hereComplex I of electron transport chain
The transfer of electons from succinate to coenzyme Q occurs hereComplex II of electron transport chain
The only complex in the electron transport chain where no hydrogen pumping takes placeComplex II
The transfer of electrons to cytochrome c from coenzyme Q occurs hereComplex III
The electron transport chain takes place hereinner membrane of the mitochondria
This shuttle produces 1.5ATP from NADH to FADH once transferred to complex IIglycerol 3-phophate shuttle
This shuttle produces 2.5ATP from NADHmalate-aspartate shuttle
This describes the direct relationship between the proton gradient and ATP synthesischemiosmotic coupling
Oxidative phosphorylation is inhibited by this conditiondecreased O2
