Which molecules help control movement of substances through cell membranes?
proteins help control movement of substances through cell membranes.
What is the function of active transport in moving small molecules and ions across cell membranes?
the movement of materials against a concentration difference is known as active transport. Active transport requires energy.
Explain the part played by the cell membrane in the movement of substances into and out of the cell?
The correct answer is diffusion. Diffusion is the process by which materials enter and leave a cell through the cell membrane.
What term refers to the movement of water molecules?
translation: as with all materials that move.
What is diffusion a natural movement of molecules from?
in the normal diffusion the substance move from the area of greater concentration to that of lower concentration. .... but i never know what do we mean be "faciliated" plz specify
The compounds in biological membranes that form a barrier to the movement of hydrophilic materials across the membranes are?
lipids
Which molecules help control movement of substances through cell membranes?
proteins help control movement of substances through cell membranes.
The movement of water and dissolved materials through cell membranes?
osmosis

What is a Diffusion is the movement of a substance?
diffusion is the movement of materials into cell membranes when the outside of the cell has a higher density than the inside
What is a passive trasport?
Passive transport is the movement of molecules through cell membranes with out the use of energy by the cell
Explain the part played by the cell membrane in the movement of substances into and out of the cell?
The correct answer is diffusion. Diffusion is the process by which materials enter and leave a cell through the cell membrane.
What is facillitated diffusion?
Facilitated diffusion is, the movement of specific molecules across cell membranes through protein channels
What term refers to the movement of water molecules?
translation: as with all materials that move.
What has the author Wilfred Donald Stein written?
Wilfred Donald Stein has written: 'The movement of molecules across cell membranes'
