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

Compartmentalization increases the efficiency of the process of cellular respiration, leading to higher energy production (ATP).  

Explanation:

In biology, compartmentalization refers to the formation of separate areas within the cell in order to carry out specific cellular functions more efficiently. In a cell, these compartments are usually delimited by lipid layer membranes. In eukaryotic cells, mitochondria (and also chloroplasts in plants) are the most important compartments in terms of metabolic processes. These organelles function to generate energy in the form of ATP by the process of cellular respiration. From an evolutionary perspective, compartmentalization increases the surface area that mitochondria use to generate energy ATP and provides a unique internal medium to carry out these metabolic reactions since oxidative phosphorylation, which the most important process in terms of energy generation, occurs in the mitochondrial matrix.
