Cell membrane components are synthesized in the endoplasmic reticulum, transported as vesicles to the Golgi apparatus where they are modified, and then are transported to the cell surface where they deliver their contents to the cells exterior and become a part of the cell membrane in a process called ____________. The reverse of this process, bringing nutrient containing particles from out side to the inside of the cell is called _________.

The ability of a cell membrane to allow hydrophilic molecules to pass into a cell is determined by:

Which of the following allows cells to pick up and concentrate a specific kind of molecule?

Diffusion of water across a selectively permeable membrane is called:

Consider the transport of protons and sucrose into a plant cell by the sucrose-proton cotransport protein. Plant cells continuously produce a proton gradient by using the energy of ATP hydrolysis to pump protons out of the cell. Why, in the absence of sucrose, do protons not move back into the cell through the sucrose-proton cotransport protein?
