What does it mean when you say a cell membrane is impermeable?
nothing can pass through it
What organelle is part of selectively permeable?
It is based on the structure of the cell membrane, which has proteins and lipids in it that make some substances impermeable to the membrane, often based on slight electrical charges and sometimes by size of the molecule or other chemical properties. Some substances require an enzyme or hormone to cross the barrier of the cell membrane, such as binding sites on cell membranes that will not allow glucose into the cell unless insulin binds with the sites, which forms a chemical bridge to allow glucose molecules to pass through the cell membrane into the cell. Without the insulin, the cell membrane is impermeable to glucose.
What Gas produced as a waste of certain bacteria can be used as fuel?
bacteria usually produce waste by a cell membrane. Cell membranes are not impermeable
If a substance is unable to diffuse across a membrane we say the membrane is?
osmotically active
If the membrane in a beaker were impermeable would the concentration of salt parts on either side of the mnrame change?
If the membrane in a beaker were impermeable the concentration of salt parts on either side will not change
What part of the body that contain impermeable membrane?
cell
All transport through the cell membrane can be classified as?

What does it mean when you say a cell membrane is impermeable?
nothing can pass through it
The part of the cell that is in most direct contact with the environment is the?
The cell membrane, which surrounds the cell and is responsible for which molecules are allowed to diffuse into or out of the cell and which molecules are impermeable to the membrane
What Component of cell membrane that makes it impermeable to water?
The cell membrane is not impermeable to water but semi permeable which means it allowa only water to enter into the cell when the concentration of water molecules is higher in the fluid surrounding the cell than the fluid inside the cell.
What is a sentence using the word impermeable?
an impermeable membrane
What is the basic strcture of a cell membrane?
Cell membrane is elastic and transparent. It can be impermeable, permeable, semi-permeable or selectively permeable. In humans the plasma membrane is selectively permeable that is it allows entry to certain substance.
What would happen to a cell if it membrane became impermeable to most substances?
It would die because of a lack of materials inside the cell
What would happen to a cell if it's membrane became impermeable to most substances?
It would die because of a lack of materials inside the cell
What would happen to a cell if it's membrane became impermeable to most substance?
It would die because of a lack of materials inside the cell
Is a cell membrane permeable impermeable or partially permeable?
Plasma membranes are selectively permeable.
Is cell wall an impermeable membrane?
No, the cell wall is easily permeable and allows most substances to enter or leave without any resistance
