Plasma membranes that have been isolated from red blood cell are not contaminted by internal cell membane?

Plasma membranes isolated from a red blood cell will not be contaminated with internal cell membrane (i.e. membrane from cell organelles - small structures found within cells) because red blood cells do not contain any organelles, so there will be no 'internal membrane' to contaminate.

Is a cell membane found in a prokayotic cell?
Yes. As a matter of fact, a cell membrane is the one thing ALL cells have in common.
What are the roles of proteins carbohydrates and cholesterol in the plasma membane?
Apple pie to the square root of the seribrim theory is equal to the roles of protains carbohydrates and cholesterol in the plasma membrane
How are the cells in a plant that carry the water adapted to their function?
Passive transport:the movement of molecules across the cell membane. Diffusion:the movement of molecules in fluid or gas form from a region of higher to a region of lower concentration( its much like how wind is created, also depeesurezation is like this to) but the one i think ur looking for is- Osmosis: the diffusion of water molecules across a semipermeable membrane from an area of higher water concentration toan area of lower water concentration.
What is the function of cell membane in movement of the substances in and out of the cell?
The cell membrane behave as a living barrier for the flow of movement of substance in and out of the cell. Cell membrane containg small pore of approximately 8-10 Ao wide pores. Thus the molecule only of this size and smaller then this can pass through the cell membrane in bulk and permeable transport. The transport although mainly occurs in two ways by passive transport in which no energy is needed and molecules or substances are transported in flow of concentration gradient. Second is active transport in which energy is needed (in eukaryotes energy is provided by ATP and in prokaryotes it is generally comes from proton motive force) and substance or molecules move against the concentration gradient e.g. Na-K exchange pump.
What is the Difference between electrochemical equivalent and chemical equivalent?
Electrochemical equivalent is one mole of ionized substance divided by its valency.It is concerned with ions. chemical equivalent is the weight of a substance that is chemically equivalent to 8.000g of oxygen
Which type of molecule forms a lipid bilayer within a cell membane?
a phospholipid
Plasma membrane does what?
The plasma membane controls what goes in and what comes out of a cell. It is like a security check point in an airport.
What plasma membrane?
The plasma membane controls what goes in and what comes out of a cell. It is like a security check point in an airport.
What does cell membane do in plant cell?
The cell membrane surrounds the cell and keeps it together. It controls the substances passing into and out of he cell.
Is a cell membane found in a prokayotic cell?
Yes. As a matter of fact, a cell membrane is the one thing ALL cells have in common.
What forms of cellular transportation helps human cell maintain a relatively constant sodium and potassium concentration?
A Cell membane Pump
What are the roles of proteins carbohydrates and cholesterol in the plasma membane?
Apple pie to the square root of the seribrim theory is equal to the roles of protains carbohydrates and cholesterol in the plasma membrane
What is space of perona in fore arm?
The fascial space of the forearm between the flexor digitorum profundus anteriorly and the pronator quadratus and the interosseous membane posteriorly is called SPACE AF PARONA. Sajid Hayaat.
Are the wings of bees and birds very similar?
No.Bird wings are made of feathers.Bee wings (and many insects) are made of a membane supported by a system of veins.Bat wings are skin webbing stretched between their "fingers".
Is cell membane a plant cell or a animal cell?
A Cell Membrane Is Both. It is What All The Components Within A Cell That Makes Up A Cell Membrane such as the cytoplasm, nucleus, vacuole, cell wall etc. a cell membrane is both animal and plant cell.
