integral proteins, because they span the membrane and thereby are able to carry nutrients across the membrane
A carrier protein (as opposed to a channel protein). An example of a carrier protein is the Na+/K+ pump.
because they a unick type of transport
Type your answer here... active transport
Facilitated diffusion because carrier proteins are being used.
depends on what type of cell you are wondering about. look up a specific cell type and then the function of the smooth ER in that cell

because they a unick type of transport
facilitated diffusion
Channel proteins, a type of transport proteins to the cells, move molecules from outside of the membrane to the inside
cellular transport nop, is passive transport
Transport proteins are the type of protein most materials move in and put of.

facilitated diffusion.
Many polar molecules and ions with the assistance of transport proteins.
Transport proteins allow the active transport of large molecules through the cellular membrane.
