Question

Choose the correct answer from the alternatives given.
Eukaryotic cells are substantially larger in volume-per-surface-area than bacterial cells. How can the eukaryotic cell membrane provide this higher rate of exchange of materials?

• A. Carrier proteins speed the rate at which a solute crosses the plasma membrane in the direction of decreasing concentration
• B. Mitochondria are concentrated near membranes to provide energy for active transport of molecules or ions
• C. Large molecules are engulfed by vesicle formation
• D. All of the above are correct

Answer 1

The correct option is D All of the above are correct

All the reasons that are given in the question account for the higher rate of exchange of materials in eukaryotic cells even though they have substantially larger in volume-per-surface-area than bacterial cells.

So, the correct answer is'All of the above are correct'.
