2.9.B—Explain how internal membranes and membrane-bound organelles contribute to compartmentalization of eukaryotic… question 1

[Maximum number: 1]

What evolutionary advantage does compartmentalization of core metabolic processes offer eukaryotes?

A

Evolution of the mitochondria allowed eukaryotes to perform respiration.

B

With the evolution of mitochondria in eukaryotes, the Krebs cycle and electron transport chain also evolved.

C

Evolution of a nucleus in eukaryotes separates the processes of transcription and translation and they can be regulated separately.

D

A nucleus in bacteria provides separation of respiration from transcription. NO TEST MATERIAL ON THIS PAGE
