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.

- A pdf file of your hand drawn, stepwise mechanisms for the reactions. For each reaction in the assignment, you must write each mechanism three times (there are 10 reactions, so 30 mechanisms). (A) do the work on a tablet and save as a pdf., it is expected to write each mechanism out and NOT copy and paste the mechanism after writing it just once. Everything should be drawn out stepwise and every bond that is formed and broken in the process of the reaction, and is expected to see all relevant lone pair electrons and curved arrows.
