If a substance is unable to diffuse across a membrane we say the membrane is?
osmotically active
What a physiological process in humans that utilizes either active transport or passive transport to generate a body function?
absorption of urea from bloodi only know one, i was hoping that someone could give some more. I know that the kidneys use active transport to absorb urea, and nitrogen from the blood. (Low concentration of urea, excess water etc. to a high concentration in the kidneys)
Is carpet urea same as nitrogen urea?
No,carpet urea is urea formaldehyde it is aproduced by treating urea with formaldehyde
Give the factors that determine the turgidity of the cells?
There are many factors that determine the turgidity, or structure, of a cell. These factors include the amount of water present in the cell, a semi-permeable membrane of the cell, and formation of an osmotically active substance within the cell.
What is the term for waste products of protein metabolism eliminated by kidneys?
No. Urea is.
What component of the molasses solution was osmotically active?
Sugar is the component of a molasses solution which is osmotically active.
Are osmotically active substances simple diffusion or active transport?
simple diffusion.
Why does glucose and Sodium chloride behave osmotic ally different?
Glucose and sodium chloride behave differently osmotically because each formula unit of glucose behaves as a single osmotically active unit, but each formula unit of sodium chloride behaves as two osmotically active units: Each formula unit dissociates in solution into two ions, and the two ions act as osmotically independent units.
If a substance is unable to diffuse across a membrane we say the membrane is?
osmotically active
What is an osmotically active substance?
It is a solute that causes osmosis to occur. For instance, if a solution contains sucrose and the membrane is impermeable to sucrose,, water will move out of the cell and into the solution to dilute it. Hence the solution is hypertonic. Sucrose would be considered an osmotically active solution in this case because it induces osmosis of water across a membrane.
What types of substances are stored by plants?
starch is one substance stored in plants because starch is not osmotically active
What happens when water is osmotically removed from a plant?
When water is osmotically removed from a plant bad things could happen. When the plant is dehydrated i could die.
