Solutes diffuse more slowly in cytoplasm than in water because of

Question

Quizplus · Accepted Answer

The presence of many crowded molecules in the cytoplasm can slow down the rate of diffusion of solutes. As the cytoplasm contains a crowded mixture of molecules such as proteins, nucleic acids, and other macromolecules, these can obstruct the movement of smaller solutes through the solution. This increases the effective viscosity of the cytoplasm, which slows down the rate of diffusion of solutes. Therefore, solutes diffuse more slowly in cytoplasm than in water. The other choices are not relevant to the slowing of diffusion in cytoplasm.
