Multiple Choice
In eukaryotic cells, the components of the electron transport chain are located in or on __________.
A
the cytosol
B
the matrix of the mitochondrion
C
the intermembrane space of the mitochondrion
D
none of the listed locations
E
the inner membrane of the mitochondrion
Verified step by step guidance1
Understand the structure of the mitochondrion: The mitochondrion has an outer membrane, an inner membrane, and spaces such as the intermembrane space and the matrix.
Learn about the electron transport chain (ETC): The ETC is a series of protein complexes and other molecules that transfer electrons through a membrane to create a proton gradient that drives ATP synthesis.
Identify the location of the ETC: In eukaryotic cells, the components of the ETC are embedded in the inner membrane of the mitochondrion.
Consider the function of the inner membrane: The inner membrane's structure is crucial for the ETC as it allows for the establishment of a proton gradient necessary for ATP production.
Review the options given: Compare the locations provided (cytosol, matrix, intermembrane space, none) with the known location of the ETC, which is the inner membrane of the mitochondrion.
