Question
Mapdei Sapling Learning Use the cellular diffusion lab to help you answer the two questions below. There is a larger number of a hydrophilic molecules on the outside of a cell than on the inside. Identify the conditions that could equalize the intracellular and extracellular concentrations of this molecule. Select all that apply. placing only intracellularly directed pumps in the membrane not inserting any transport proteins in the membrane placing channel proteins in the membrane placing intracellularly directed and extracellularly directed pumps in the membrane which of the conditions would be the most efficient way for a cell to equalize the intracellular and extracellular concentrations of this molecule? O placing only intracellularly directed pumps in the membrane O not inserting any transport proteins in the membrane O placing channel proteins in the membrane O placing intracellularly directed and extracellularly directed pumps in the membrane Previous check Answer o Next ExilExplanation / Answer
Answer 1: Option C
By placing the channels, the molecules can move from high to lower concentration side. This way movement can take place both ways and equilibrium can be attained.
Answer 2: Option C
Here also the option is same. This is because the question says metabolically efficient and channels don't use ATP or any form of energy for movement of molecules. Channels allow facilitated diffusion, which is metabolically efficient method.
