where is the electron transport chain located? It is located in the inner mitochondria membrane
The mitochondria is the ______ of the cell power house
what does NADH stand for? Nicotinamide Adenine Dinucleotide
what does FADH stand for? Flavin Adenine Dinucleotide
Cells use ________ system made up of proteins inside mitochondria to generate ATP proton-pumping system
what is the function of an electron in the electron transport chain? To use its free energy to pump against their concentration gradient
what is a cytochrome? cytochrome are heme proteins. They serve as electron carriers in oxidation-reduction reactions
The electron transport chain pumps protons out of the _______ mitochondrial matrix
Cytochrome oxidase can function in the ________ of oxygen absence
what does the electron transport chain accomplish in cells? It generates 28 out of the 32 ATPs obtained from glucose catabolism
what is ATP synthetase? It is an enzyme that converts the free energy of the proton gradient to chemical energy in form of ATP
Enzymes of the ETC are embedded in the inner membrane in association with enzymes from ______ oxidative phosphorylation
Cytochrome oxidase (complex IV) accepts electrons from _______? Cytochrome c
Complex I is also called _______? dehydrogenase
Coenzyme Q accepts electrons from ________ and ______ complex I and complex II
when succinate is oxidized protons are pumped at _________ Complex IV
Complex I donates two electrons to ________ Coenzyme Q
Complex II accepts two electrons from _______ of succinate dehydrogenase of the TCA cycle FADH2
The electron in electron transport chain derived from various substances are transferred to _____ oxygen
Coenzyme Q is also known as _________ Ubiquinone
Complex II also known as _________ Sussinate Dehydrogenase
NADH is oxidized by ________ CoQ
Cytochrme b is oxidized by ____________ cytochrome c1
Cytochrome a is oxidized by __________ oxygen
The oxidation of NADH yeild about ________ ATP 3

What do you understand by Oxidative Phosphorylation? it is the main source of energy in Aerobic metabolism
what is the process of adding phosphate to ADP called? Phosphorylation
What happens during oxidative phosphorylation? There is the production of ATP using transfer of electrons from energy
How is energy captured in oxidative Phosphorylation? The energy is captured in the form of a proton gradient across the inner mitochondrial membrane.
what is the function of ATP synthase? ATP synthase uses energy from proton flow across F0 subunit to synthesize ATP
