What is the process called when molecules must join with another molecule such as a protein to get through a membrane?
The process is called facilitated diffusion. It is a type of passive transport that involves the movement of molecules across a membrane with the help of specific proteins called carrier proteins or channel proteins. These proteins assist the molecules in crossing the membrane by providing a pathway.
What are facts about passive transport?
The transport of molecules across the plasma membrane of a living cell by a process that involves a specific transmembrane carrier
Why would facilitated diffusion picture?
Facilitated diffusion is used when molecules are too large or polar to pass through the cell membrane on their own. It involves the help of carrier proteins that aid in transporting specific molecules across the membrane down their concentration gradient. This process does not require energy input from the cell.
How does facilitated diffusion work?
Facilitated diffusion is a process where molecules move across a cell membrane with the help of transport proteins. These proteins create a channel or carrier to allow specific molecules to pass through the membrane. This movement is passive and follows the concentration gradient, meaning that molecules move from an area of high concentration to low concentration.
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.
What does a carrier protein do in the process of transporting molecules across a cell membrane?
A carrier protein helps transport molecules across a cell membrane by binding to specific molecules and changing shape to move them across the membrane.

What carrier molecules are involved in the process of what type of diffusion?
Carrier molecules are not involved.Different between chemical potential leads the diffusion
How do carrier proteins facilitate the passive transport of molecules across a membrane?
Carrier proteins facilitate the passive transport of molecules across a membrane by binding to specific molecules on one side of the membrane and changing shape to transport the molecules across to the other side. This process does not require energy and is driven by the concentration gradient of the molecules.

How does a sample of sulfur form crystals when it undergoes a specific process?
When a sample of sulfur undergoes a specific process called crystallization, its molecules arrange themselves in an orderly pattern to form crystals. This process involves cooling the molten sulfur slowly, allowing the molecules to align and solidify into a crystalline structure.
What cellular process leads to the production milk-specific mRNA molecules?
The process of lactation in mammary epithelial cells involves the upregulation of specific genes, including those responsible for producing milk-specific mRNA molecules. This process is controlled by hormones such as prolactin and glucocorticoids, which stimulate the expression of genes involved in milk production. The milk-specific mRNA molecules are then translated into proteins needed for milk synthesis.
How do carrier proteins transport substances across membranes?
Carrier proteins bind to specific molecules on one side of the membrane, undergo a conformational change, and release the molecules on the other side. This process allows the substances to be transported across the membrane selectively.
Which form of endocytosis involves a receptor?
Receptor-mediated endocytosis is the form of endocytosis that involves specific receptors on the cell membrane binding to ligands for internalization. This process allows for selective uptake of specific molecules into the cell.
