(a)
Interpretation:
Whether the change
Concept Introduction:
Electron transport chain is a sequence of biochemical reactions in which electrons and hydrogen atoms from the citric acid cycle are transferred to various intermediate carriers and finally reacts with molecular oxygen to form a water molecule.
There are four complexes associated with the electron transport chain that is present in the inner mitochondrial membrane. The four complexes that help in the electron transfer in the electron transport chain are:
Complex I:
Complex II:
Complex III:
Complex IV:
An overview of the electron transport chain is as follows:
Redox
Here, A is oxidized form and AH is reduced form.

An overview of the electron transport chain is as follows:
Redox reactions involve oxidation and reduction reaction occurring simultaneously so that one species is oxidized and the other one is reduced. The species that gain hydrogen or electron is known as reduced form and the species that loss hydrogen or electron is known as oxidized form. The general representation of redox reaction is,
Here, A is oxidized form and AH is reduced form.
