To prevent osmotic flow of water across the membrane pressure sould be applied to which solution?
The solution on the "receiving side" of the membrane, ie the side to which you are trying to prevent osmotic flow.
The transport of a substance across the cell membrane against its concentration gradient is called what?
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
What is meant by passive transport of material across a membrane?
"Passive" mean that it does not require energy, therefore the passive transport of material across the membrane means that it can transport the material (cells or whatever) without the function of energy across the membrane.
What two forces drive the passive transport of ions across a membrane?
Two forces drive the passive transport of ions across a membrane: -the concentration gradient of the ions -the effect of membrane potential (voltage) on the ions
A solutions osmotic pressure differs from its hydrostatic pressure in that osmotic pressure is the force which pulls water across a membrane resulting from?
osmotic pressure is not the pressure which pulls the water , it is the other way round. It is the pressure with which the water molecule travel across the semi-permeable membrane. Hydrostatic pressure as the name suggests is the pressure due to the "standing column of water and not due to the movement
The cell mechanism of active transport involves the transport of insoluble chemicals across the membrane with protein acting as the carrier?
true
What is the mechanism for absorption of water across the intestinal epithelium?
Osmotic gradients control the inflow and outflow of water across any membrane, whether epithelium or phospholipid barrier.
Is it true that the cell mechanism of active transport involves the transport of insoluble chemicals across the membrane with protein acting as the carrier?
yes
The cell mechanism of active transport involves the transport of insoluble chemicals across the membrane with protein acting as the carrier. true or false?
true
To prevent osmotic flow of water across the membrane pressure sould be applied to which solution?
The solution on the "receiving side" of the membrane, ie the side to which you are trying to prevent osmotic flow.
Why tonicity is important?
because it refers to the effect of the solutions osmotic pressure has on water movement across the cell membrane of cells with in the solution. because it refers to the effect of the solutions osmotic pressure has on water movement across the cell membrane of cells with in the solution.
What is the transport of water across the cell membrane called?
Movement of water across a membrane is called OSMOSIS.
What biomolecule helps transport molecules across the membrane?
proteins
