WebThe inner membrane cristae form deep invaginations that carry respiratory chain complexes and the ATP synthase. It has remained enigmatic how crista junctions that connect inner … NADH is oxidized into NAD , H ions, and electrons by an enzyme. FADH2 is also oxidized into H ions, electrons, and FAD. As those electrons travel farther through the electron transport chain in the inner membrane, energy is gradually released and used to pump the hydrogen ions from the splitting of NADH and FADH2 into the space between the inner membrane and the outer membrane (called the intermembrane space), creating an electrochemical gradient.
WebATP synthase complex (F o F 1-ATP synthase). This complex allows protons to flow back into the matrix and uses the free energy change from this process to synthesize ATP from ADP and inorganic phosphate (P i).It is located in knob-shaped structures embedded in the cristae (invaginations of the inner mitochondrial membrane) and extending into matrix.
