What acts like the gatekeeper-allowing some materials to pass throuh the cell but not others?
The cell membrane acts as the gatekeeper, selectively allowing some materials to pass through while restricting others. It is primarily composed of a phospholipid bilayer with embedded proteins that facilitate transport. This selective permeability ensures that essential nutrients enter the cell and waste products exit, maintaining the cell's internal environment. Additionally, the presence of transport proteins and channels further regulates the movement of specific molecules.
What else can I help you with?
What confines cell contents and regulates entry and exit of materials?
The cell membrane confines cell contents and regulates the entry and exit of materials. It acts as a selectively permeable barrier, allowing certain compounds to pass while preventing others from entering or exiting the cell.
What carries materials through the cells acts in making proteins?
You you may mean a ribosome, which carries RNA and acts in making proteins.
Controls the entry or exit of cellular materials?
Cell membrane regulates the entry and exit of cellular materials. It acts as a selective barrier, allowing certain substances to pass through while restricting the movement of others. Transport proteins embedded in the membrane play a key role in facilitating the transport of specific molecules in and out of the cell.
What structure regulates the traffic of materials into and out of the cell?
The cell membrane, also known as the plasma membrane, regulates the traffic of materials into and out of the cell. It acts as a selectively permeable barrier that allows certain substances to pass through while restricting others.
Where do plant cells store their dissolved materials such as salts and sugars?
Plant cells store their dissolved materials, such as salts and sugars, in their vacuoles. The vacuole is a membrane-bound organelle that acts as a storage compartment for various substances in the plant cell.
Is the apartment complex responsible if your car was shot up on their property?
It would not be responsible for the criminal acts of others unless it was somehow at fault.It would not be responsible for the criminal acts of others unless it was somehow at fault.It would not be responsible for the criminal acts of others unless it was somehow at fault.It would not be responsible for the criminal acts of others unless it was somehow at fault.
What were some others acts in the 1770s?

Function of water?

What does it mean when your husband acts like hes like you around?
he acts the same way around others the same way he acts to you
What is force that acts between two materials as they slide over each other?
Friction is the force that acts between two materials as they slide over each other. It opposes the relative motion of the materials and is influenced by the roughness and the nature of the surfaces in contact.
What confines cell contents and regulates entry and exit of materials?
The cell membrane confines cell contents and regulates the entry and exit of materials. It acts as a selectively permeable barrier, allowing certain compounds to pass while preventing others from entering or exiting the cell.
What organelle controls the exchange of materials between the cell and its environment?
The plasma membrane controls the exchange of materials between the cell and its environment. It acts as a selectively permeable barrier that allows certain substances to enter and exit the cell while restricting others.
What carries materials through the cells acts in making proteins?
You you may mean a ribosome, which carries RNA and acts in making proteins.
What is a know-it-all?
Someone who acts as if they know everything and others do not.
What effect did Thurgood Marshall have?
How did Thurgood's acts effect others?
What allows some materials to pass through it but keeps other materials out?
A selectively permeable membrane allows only certain molecules or substances to pass through, based on their size, charge, or other properties. This membrane acts as a barrier that can control the passage of specific substances while blocking others.
What type of properties describe how one material acts on other materials?
Chemical Properties.
