Compared with prokaryotic cells, what functional advantage do eukaryotes gain from housing reactions inside separate membrane bound compartments?

A.Genetic information gains complete protection from mutation
B.Reactions inside organelles escape ordinary thermodynamic limits
C.Each organelle replicates the full genome as a backup system
D.Incompatible processes run simultaneously, each under its own optimized pH and enzyme mix

Explanation

Core Concept

Eukaryotic cells use membrane-bound organelles to create distinct chemical environments and localize enzymes and substrates. Prokaryotes typically lack those membrane-bound organelles, but they still contain specialized internal regions and molecular assemblies that organize cellular processes. The difference is therefore degree and mechanism of compartmentalization, not 'organized eukaryote versus undivided prokaryote.'

Correct Answer

DIncompatible processes run simultaneously, each under its own optimized pH and enzyme mix
