Final answer:
Each component mentioned is located in specific compartments of a mitochondrion: porins in the outer membrane, both the mitochondrial genome and citric acid cycle enzymes in the matrix, and the proteins of the electron-transport chain, ATP synthase, and the membrane transport protein for pyruvate in the inner membrane. Option B is correct.
Step-by-step explanation:
In which of the four compartments of a mitochondrion are each of the following located?
A. Porin - Porins are located in the outer mitochondrial membrane.
B. The mitochondrial genome - The mitochondrial DNA is located in the mitochondrial matrix.
C. Citric acid cycle enzymes - Enzymes of the citric acid cycle, also known as the Krebs cycle, are located in the mitochondrial matrix.
D. Proteins of the electron-transport chain - Proteins that make up the electron transport chain are embedded in the inner mitochondrial membrane.
E. ATP synthase - ATP synthase is located in the inner mitochondrial membrane.
F. Membrane transport protein for pyruvate - This transport protein is also embedded in the inner mitochondrial membrane.
Moreover, in the context of electron transport systems in prokaryotes, they are located in the cytoplasmic membrane, as prokaryotes do not have mitochondria.
