There are two main ways in which molecules are transported into and out of cells - active transport and passive transport. which of the following statements is true of passive transport?

Because a cell's membrane is composed of fat, only fat-soluble molecules are able to dissolve through the membrane into the cytosol. There are two main ways in which molecules are transported into and out of cells - active transport and passive transport.

The following statement is true about passive transport: carrier proteins are sometimes used during passive transport.

Explanation:

There are two man ways in which molecules are transported into and out of cells; active transport and passive transport. While active transport requires an input of cellular energy, passive transport does not. In passive transport the molecules can move freely in and out of the cell, through the cell membranes, through simple processes such as diffusion or osmosis. Sometimes, when the molecules are moving too slowly, the cell uses carrier proteins as channels to help the movement along.

hope this !

c is the correct answer hope this !
