Mention the important series of events of aerobic respiration that occur in the matrix of the mitochondrion as well as one that take place in inner membrane of the mitochondrion.

Explanation

Krebs' cycle occurs in the matrix of mitochondria. It is depicted in the following seires of reactions

Eelectron transport chain is carried in the inner mitochondria membrane
The inner mitochondrial membrane is specific about possessing proton `(H^(+))` and electron `(e^(-))` acceptors in a particular sequence called electron transport chain . It has four enzyme compleses.
The electrons either follow the pathway of complexs I, III and IV or II, III and IV depending upon the substrates from Krebs' cycle.
The transfer of electron and hydrogen atoms takes place in the following way
Complex I consists of flavoproteins of NADH dehydrogenase `(FP_(N))` of which FMN is the prosthetic group . Combined with the flavoprotein is non-heme iron of NADH dehydrogenase. This complex spans inner mitochondrial membrane and is able to translocate protons across it from matrix side to outer side.
Complex II Consists of flavoprotein of succinate dehydrogenase. of which FAD is the prosthetic group . Combined with the flavoprotein is non-heme iron of succinate dehydrogenas.
Between complexs II and III is the mobile carrier coenzume -Q (CO-Q) or ubiquinon (UQ)
Complex III Constists fo cytochrome-b and cytochrome`-c_(1)`. Associated with cytochrome-b is non-heme iron of complex III. Between complex III and IV is the mobile carrier cytochrome-c
Complex IV Consists of cytochrome-a and cytochrome`-a_(3)` and bound copper that are required for this complex reaction to occur. This cytochrome also called cytochrome oxidase, is the only electron carrier in which the heme irons has a free ligand that can react directly with molecular oxygen

Thus, hydride ions are transferred from the substance to be oxidised to `NAD^(+)` From `NAD^(+)` the hydrogen atoms are transferred to FMN of flavoprotein 1 (Fp'N). After FMN the hydrogen atom undergoes ionisation, i.e., it splits into an electron and a proton
In further stages there is no longer a transfer of hydrogens but of electorns. The electron passes to co-enzyme -Q. and from co-enzyme Q to cytochromes-`b-,c_(1)c,a,` a and a_(3).` The proton is released free.
As the hydrogen atom or electron passes down by `F_(0)-F_(1)` particle the chain, there is simultaneous oxidation of one coenyme and reduction at another steps. Oxygen is able to diffucise indside the mitochondria.
It is converted to anionic from `O_(2)^(-)` , combines with `2H^(+)` and forms metabolic water reduced co-enzyme `NADH+H^(+)` helps in pushing out three pairs of `H^(+)` to outer chamber while `FADH_(2)` sends two pairs of `H^(+)` to outer chamber
Oxidative phosphorylation is the synthesis of energy rich ATP molecules wiht the help of help liberated during oxidation of reduced co-enxyme `(NDH_(2),FADH_(2))` produced in respiration. The enzyme required for this syntheis is called ATP synthesis is called ATP synthase present in inner mitocchondra membrnane.
