Baker’s Yeast: The Advantages of Compartmentation
A breakthrough occurred in the history of cells about 1.5 billion years ago. Simple, bacteria-like organisms had been around at least 2 billion years when a radically new design of the cell body appeared. These new cells were filled with small, separate compartments, each fully surrounded by a watertight lipid bilayer. The advantage of internal compartmentation is profound: the different functions of the cell can be performed in specialized locations. All of the molecular machinery of transcription or of oxidative phosphorylation can be concentrated in one place, allowing more efficient performance and finer control.
