2. Biological Oxidation
Electron Transport
Chain (ETC)
Mechanism Involved
in ETC.

3. Oxidation is loss of electrons
and reduction is gain of
electrons.
This general idea is
applicable for biological
systems.
In biological system some
reducing equivalents
involves.
In which NAD+, FAD and
FMN are common.

5.  Carbohydrates, fatty acids and amino
acids undergo a series of metabolic
reactions and, get oxidized to CO2 and
H2O.
 Reducing equivalents are transferred to
coenzymes NAD+ and FAD to produce
NADH and FADH2 coenzymes by
passing from ETC.
