The synthesis of $ATP$ in photosynthesis and respiration is essentially an oxidation-reduction process involving the removal of energy from:

Iron-containing compounds are .......

Which mineral elements are essential for the process of respiration?

The process by which $ATP$ is produced in the inner membrane of a mitochondrion,where the electron transport system transfers protons from the inner compartment to the outer,and as the protons flow back to the inner compartment,the energy of their movement is used to add phosphate to $ADP$,forming $ATP$,is known as:

Match the electron carriers and reduced substances in Column $I$ with respiratory complexes in Column $II$. Choose the correct option given below.

Column $I$	Column $II$
$i.$ $FADH_2$	$a.$ Complex $III$
$ii.$ Ubiquinol	$b.$ Complex $IV$
$iii.$ $NADH + H^{+}$	$c.$ Complex $II$
$iv.$ Cytochrome $C$	$d.$ Complex $I$
