Based on the "A Panoramic View of the Eukaryotic Cell" section, which statement accurately describes the characteristics and functions of membranes within eukaryotic cells?

  • A: Eukaryotic cells have extensive internal membranes that divide the cell into compartments, allowing for specialized metabolic functions.
  • B: The basic fabric of most biological membranes is a triple layer of phospholipids and lipids.
  • C: All enzymes involved in cellular metabolism are freely dissolved in the cytoplasm, not embedded in membranes.
  • D: Plasma membranes are primarily responsible for increasing cellular volume without affecting surface area.

Explanation

The text states: "a eukaryotic cell has extensive, elaborately arranged internal membranes that divide the cell into compartments—the organelles mentioned earlier. The cell’s compartments provide different local environments that support specific metabolic functions, so incompatible processes can occur simultaneously in a single cell."
