Question

A cell uses many methods to transport solutes across the plasma membrane. Classify the following descriptions as either Simple Diffusion, Facililated diffusion, Active transport, or bulk transport.

-movement of solutes into the cell down their conectration gradient using membrane proteins.
-movement of solutes into the cell against their concentration gradient using membrane proteins.
-movement of contents of transport vesicles into the cell by endocytosis
-movement of solutes into the clel directly through the plasma membrane

Explanation / Answer

1. movement of solutes into the cell down their conectration gradient using membrane proteins. is called Facililated diffusion,
2. movement of solutes into the cell against their concentration gradient using membrane proteins is alled active transport.

3. movement of contents of transport vesicles into the cell by endocytosis is called bulk transport.
4. movement of solutes into the clel directly through the plasma membrane is called Simple Diffusion.
