Oxidative Phosphorylation

_______________ captures the energy of high-energy ________________ to synthesize ATP

Oxidative phosphorylation, electrons

The flow of electrons from __________________ occurs in the ______________ or respiratory chain.

NADH and FADH2 to O2, electron-transport chain

This exergonic set of oxidation-reduction reactions generates a ______________. which is used to power the synthesis of __________________

proton gradient, ATP

Collectively, the ___________________ are called cellular respiration or simply respiration.

citric acid cycle and oxidative phosphorylation

Metabolic fuels such as glucose, fatty acids, and amino acids, as well as the oxidation of acetyl carbons to CO2 via the citric acid cycle, yield the reduced cofactors _________________ (ubiquinol (QH2)), which get reoxidized, ultimately releasing free energy. That free energy is harvested to synthesize ATP, a phenomenon called __________________________

NADH and FADH2, oxidative phosphorylation

___________________ is the largest of the electron transport proteins in the mitochondrial respiratory chain
