What else can I help you with?
What are the special structures in the cell membrane that allow materials such as water and sugar through made of?
PROTEIN!!!!!!!!!!!!!!!!!!!!!!!!!
What proteins act like selective passageways in the cell membrane?
The lipid bilayer is a tightly packed membrane of hydrophobic (dont like water) molecules, so only hydrophobic or very very small molecules can go directly through it. Large molecules such as hormones need to have a special hole in the membrane that they can fit through, but some are so large that if the membrane created a plain old hole, everything would be able to fit through, even things the cell doesnt want. The proteins create special openings that allow only a specific variety of molcule to go through, like only a special type of hormone. They work a lot like a lock and key, so when the molecule encounters its protein, it acts like a key and opens the portal. once the molecule passes, the protein closes the opening and nothing else can go through.
How water molucleus move through the cell membrane doing out mosis?
Water molecules move through the cell membrane via osmosis, a passive process where water flows from an area of low solute concentration to an area of high solute concentration. This movement occurs through special proteins called aquaporins that facilitate the transport of water across the membrane. The process helps maintain the balance of water inside and outside the cell.
Does osmosis require membrane proteins?
No, osmosis is a special type of diffusion in which a water molecule is able to passively transport through a membrane without a protein. Although it is polar, it's extremely small size makes this possible
What is phospholipid bilayer of the cell membrane least permeable to?
The phospholipid bilayer of the cell membrane is least permeable to charged molecules such as ions and large molecules like proteins. These molecules have difficulty crossing the hydrophobic interior of the lipid bilayer.
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called?
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called facilitated diffusion. In this process, carrier proteins aid in the movement of glucose across the membrane down its concentration gradient.
When molecules pass through a cell membrane using special proteins called transport proteins?
When molecules pass through a cell membrane using special proteins called transport proteins, this process is known as facilitated diffusion or active transport, depending on whether energy is required. Transport proteins help move substances across the membrane by forming channels or carriers that allow specific molecules, such as glucose or ions, to enter or exit the cell. This mechanism ensures that essential nutrients are absorbed while waste products are expelled, maintaining cellular homeostasis.
What are the special doorways in the cell membrane made of?
Special doorways in the cell membrane are made of proteins called ion channels or transporters. These proteins allow specific ions or molecules to pass through the cell membrane, regulating the movement of substances in and out of the cell.
A type of passive transport across a cell membrane that requires special carriers is?
Facilitated diffusion is a type of passive transport that requires special carrier proteins to help molecules move across the cell membrane. These carrier proteins assist in the movement of specific molecules that cannot cross the membrane on their own.
In facilitated diffusion what are the special channels that help substances cross the cell membrane made of?
In facilitated diffusion, the special channels that help substances cross the cell membrane are typically made of proteins. These proteins can be integral membrane proteins that create specific pathways or channels, allowing certain molecules, such as ions or glucose, to pass through the lipid bilayer. The process is selective, as the channels are designed to accommodate specific substrates based on size and charge.
What are the special structures in the cell membrane that allow materials such as water and sugar through made of?
PROTEIN!!!!!!!!!!!!!!!!!!!!!!!!!
A special molecule that uses energy to push molecules through a membrane of a cell is called?
The special molecule is called ATP, which stands for adenosine triphosphate. ATP provides the necessary energy to power transport proteins in the cell membrane to move molecules across it.
Is not a function of protein in a cell membrane?
Proteins in the cell membrane serve several functions, including transport of molecules, cell signaling, cell recognition, and cell adhesion. They are not primarily involved in providing energy for the cell.
What are the special structures in the cell membrane that allow materials such as water and sugar to pass through made o?
The special structures in the cell membrane that allow materials like water and sugar to pass through are proteins called transport proteins. These proteins help facilitate the movement of specific molecules across the membrane by acting as channels or carriers. They play a crucial role in regulating the flow of substances in and out of the cell.
Does facilitated diffusion require the use of special membrane proteins?
no
