What else can I help you with?
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
What does it mean if a cell membrane is selectively permiable?
The cell membrane only allows certain molecules through.
What is a semipermeable mebrane?
The cell membrane is called as semi-permeable membrane because it allows only certain/selective molecules to pass through it.It mostly allows only solvent molecules to pass.It is sometimes also called as selectively permeable membrane.
Can steriods and cholesterol cross the cell membrane on their own?
Yes because the cell membrane allows non polar molecules through
What allows and blocks materials from entering a cell?
The cell membrane allows small, uncharged molecules like oxygen and carbon dioxide to pass through freely. Larger molecules and charged ions require specific protein channels or transporters in the cell membrane to enter. The cell membrane blocks large molecules, charged ions, and hydrophilic molecules from freely crossing.
How is osmosis related to solution types?
We define Osmosis as the passage of water from a dilute solution via a membrane which is semi permeable to a more concentrate solution. It means that Semi permeable membrane is a very thin layer of material which allows some molecule to pass through them and prevent some molecule from pass through them. These molecules are decided by the type of solution. Generally, the membrane only allows movement of H2O molecules. So, if on one side is a saturated solution of something while on the other side is a dilute solution, the movement of molecules will be from both the directions but net result will be from saturated to dilute solution.
What part of the cell membrane allows small molecules to pass through?
the cell membrane
What is meant by membrane is membrane?
a partially permeable membrane allows some molecules or ions to pass through it
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
What do you call a cell membrane that allows certain molecules to pass through?
A selectively permeable membrane.
What does it mean if a cell membrane is selectively permiable?
The cell membrane only allows certain molecules through.
Why does osmosis require a semipermeable membrane?
Semi permeable membrane means a very thin layer of material which allows some molecule to pass through them and prevent some molecule to pass through them. Osmosis is the passage of water from a dilute solution via a membrane which is semi permeable to a more concentrate solution. So the membrane should be semi-permeable so as to only allow the movement of H2O molecules and not the other molecules of the mixture.
Why can't charged molecules pass through the membrane?
Charged molecules cannot pass through the membrane because the membrane is selectively permeable, meaning it only allows certain substances to pass through based on their size and charge. The charged molecules are repelled by the hydrophobic interior of the membrane, which prevents them from crossing.
What is the term for a membrane that allows certain but not all molecules to diffuse through it?
semi-permeable.
In osmosis which membrane provides net movement of water without movement of NaCl?
A selectively permeable membrane allows water molecules to pass through but restricts the movement of larger solute particles like NaCl. In osmosis, water will move from a dilute solution to a concentrated solution through the membrane, causing a net movement of water without the movement of NaCl.
