How do molecules get into cells
WebLiked to exterior walls of a house, the plasma membrane is semi-permeable. In much the sam way that doors and windows allow requirement to enter one house, various proteins that span the mobile membrane permit selected molecules into the cell, although they may require some energy input to accomplish this task (Figure 2). WebWater, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as method for essential small molecules to cross the cell membrane.
