Does osmosis require a protein for water to move in and out of the cell? How do marine organisms use the process of osmosis? Why can hydrophobic molecules cross the cell membrane? Explain and give examples of cellular transport such as osmosis, active transport, simple diffusion and ...
Osmosis:Osmosis is the movement of water molecules from an area of high water concentration to an area of low water concentration. If a cell is immersed in a dilute (hypotonic) solution, water will enter the cell through the cell membrane. The cell...
In passive transport across a membrane, when two protein molecules move in opposite direction it is called as View Solution Transport ofNa+/K+across the membrane is View Solution Exams IIT JEE NEET UP Board Bihar Board CBSE Free Textbook Solutions ...
which reduces their numbers. This in turn increases the tendency of the water to flow into that side from the other side. To anthropomorphize slightly, the greater the difference in concentration of water molecules, the more they "want" to move across the barrier to the side containing the ...
And because the one side of the arm is crowded with sugar, pure water from the other side decides to move on over to make the concentration more equal or until the osmotic pressure (the pressure that happens as the molecules move) is reached [source: Encyclopedia Brittanica]. So there you...
While molecules in diffusion move down a concentration gradient, molecules during osmosis both move down a concentration gradient as well as across it. Both diffusion, and osmosis are types of passive transport, which do not require help. 1016 Words 5 Pages Better Essays Read More Osmosis and ...
Answer to: Explain how the oxygen molecules move from air into blood. List the type of cells and molecules involved in this process. By signing up,...
Water molecules are naturally attracted and stick to each other because of this polarity, forming a hydrogen bond. This hydrogen bond is the reason behind many of water's special properties, such as the fact that it's denser in its liquid state than in its solid state (ice floats on ...
While molecules in diffusion move down a concentration gradient, molecules during osmosis both move down a concentration gradient as well as across it. Both diffusion, and osmosis are types of passive transport, which do not require help. 1016 Words 5 Pages Better Essays Read More Neutral Red ...
Since a solute will not move in osmosis, how can the space between plasmolysed cells be filled by a hypertonic solution? Biological membranes are said to be selectively permeable (or semi-permeable). What does this term mean, and how does this affect the way tha...
