In cellular respiration, the electron transport chain takes place in
|
|
the outer membrane of the mitochondrion
|
|
|
the inner membrane mitochondrion
|
|
|
the cytoplasm
|
|
|
the cell nucleus
|
Explanation:
Detailed explanation-1: -The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation . It occurs in mitochondria in both cellular respiration and photosynthesis.
Detailed explanation-2: -The ETC is embedded within the extensive inner membrane of the mitochondrion, in close proximity to the mitochondrial matrix in which the TCA cycle is localized (Fig. 1).
Detailed explanation-3: -The electron transport chain associated with oxidative phosphorylation is located in the inner membrane of the mitochondria.
