Polysaccharides cross the plasma membrane through diffusion?
Yes, carbohydrates can diffuse through a plasma membrane. Proteins can also pass through the fluid membrane, as well as a few other things.
Gases such as oxygen and carbon dioxide cross the plasma membrane by?
passive diffusion through the lipid bilayer
What does NOT influence the rate of diffusion of a chemical across a plasma membrane?
Besides the concentration of the chemical, the pore size of the plasma membrane, and the osmotic pressure of the cytoplasm - nothing else influences the rate of diffusion of a chemical across a plasma membrane.
What molecule crosses the plasma membrane by diffusion?
water
How does nitric oxide cross the plasma membrane?
Simple Diffusion
Water passes through a cell membrane by?
What_is_the_passage_of_water_through_cell_membranes_calledPassage of water through cell membranes occurs through osmosis.
What is a transport process by which gases move through a membrane?
Simple Diffusion
What is diffusion and how does it relate to plasma membrane?
Diffusion is simply the movement of one molecule from an area of high concentration to low concentration. It is semi related to the plasma membrane because plasma membrane does allow diffusion, to an extent. Plasma membrane is semipermeable and only allows certain things to diffuse in or diffuse out.
