Admin Why is it important for a cell to be selectively permeable?
Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell. This is important for the cell to maintain its internal order irrespective of the changes to the environment. Movement across a selectively permeable membrane can occur actively or passively.
Why would it be a problem if cell membranes were not selectively permeable?
what would happen if cell membranes were not selectively permeable? it would not control the flow of liquid in and out of the cell so if too much gets in the cell it dies and if too much liquid leave the cell it dies. some cells need more energy then others.
What would happen if no cell membrane?
Without the nuclear membrane the cell would collapse and die. Without the cell membrane, any chemical would be allowed to enter. Membranes are very important because they help protect the cell. Materials move across the membrane by diffusion.
What would happen if cell membranes suddenly became permeable instead of selectively permeable could cells remain alive?
If the membrane were fully permeable to all substances, then anything could enter the cell. This would upset the balance between the cell’s contents and the outside environment. There is only so much ability to store substances and utilize substances, therefore, the cell would not be able to maintain homeostasis.
What might happen to a cell if it lost its selectively permeable?
A cell would be affected if it lost the ability to be selectively permeable because the cell would die and no longer exist. What might happen to a cell if it no longer can produce cholesterol? What might happen If the cell can no longer produce cholesterol is that it cannot maintain homeostasis.
What determines the permeability of a cell?
Permeability in a cell is determined by the concentration of certain group of ions inside and outside the cell . And because of this permeability , cells take up the food and water they need for survival and functioning .
What would happen if the membrane of a nucleus becomes permeable?
It would die as harmful substances entered the cellsIf the membrane of a nucleus becomes permeable to most substances, it would eventually burst due to over-bulging. What is an example of a selectively permeable membrane?
