Lekcja 8: Kompartmentacja komórki i jej pochodzenie

Cell compartmentalization

The following is an excerpt from the press release announcing the 2013 Nobel Prize in Physiology or Medicine.

Eukaryotic cells differ from prokaryotic cells by their more complex intracellular organization. In eukaryotes, specific cellular functions are compartmentalized into the cell nucleus and organelles surrounded by intracellular membranes. This compartmentalization vastly improves the efficiency of many cellular functions and prevents potentially dangerous molecules from roaming freely within the cell.

Which of the following best explains how compartmentalization within a cell “improves the efficiency” of cellular processes?

(Choice A)
A compartmentalized cell has external membranes that decrease competing interactions within the cell.
(Choice B)
Compartmentalization within a cell results in a high surface-area-to-volume ratio.
(Choice C)
Compartmentalization within a cell minimizes the surface area where cellular processes occur.
(Choice D)
A compartmentalized cell has internal membranes that increase competing interactions within the cell.
