What else can I help you with?
What allows the passage of small molecules between animal cells?
Gap junctions allow the passage of small molecules and ions between animal cells. They consist of protein channels that connect the cytoplasm of adjacent cells, facilitating communication and the exchange of signaling molecules.
Why do you have diffusion?
so molecules can use protein channel to cross a cell membrane-cleo
A junction that is a protein channel linking the cytoplasms of adjacent cells is called?
A junction that is a protein channel linking the cytoplasms of adjacent cells is called a gap junction. This structure allows for direct communication and sharing of ions and small molecules between neighboring cells.
What is a school analogy for channel protein?
A school analogy for a channel protein is a hallway with a designated passageway. Just as a channel protein serves as a selectively permeable pathway for specific molecules across a cell membrane, the hallway provides a specific pathway for students to move through and reach their designated classrooms. Other types of molecules or students may be excluded from entering the pathway, ensuring only the intended molecules or students can pass through.
Water passes quickly through cell membranes because?
The cell membrane has two phospholipids, with hydrophilic (water-loving) heads facing the outside while the hydrophobic tails point in. Water cannot pass through because of this characteristic. The hydrophilic "heads" attract water since they are polar, but the hydrophobic "tails" are non polar and reject water. H20 passes by means of a channel protein.
Is an aquaporin a type of channel protein?
Yes, an aquaporin is a type of channel protein that allows the passage of water molecules across cell membranes.
How can a gated channel protein be opened to allow the passage of molecules?
A gated channel protein can be opened by specific signals or changes in the cell environment, such as binding of a molecule or changes in voltage. This triggers the channel to change its shape, allowing molecules to pass through.
What does a channel protein do in the context of cellular transport?
A channel protein helps facilitate the passage of specific molecules or ions across a cell membrane, allowing for efficient and selective transport in and out of the cell.
What allows the passage of small molecules between animal cells?
Gap junctions allow the passage of small molecules and ions between animal cells. They consist of protein channels that connect the cytoplasm of adjacent cells, facilitating communication and the exchange of signaling molecules.
How does facilitated diffusion occur through a protein channel?
Facilitated diffusion occurs through a protein channel by allowing specific molecules to pass through the cell membrane with the help of a protein channel. The protein channel acts as a tunnel that facilitates the movement of molecules that are too large or polar to pass through the membrane on their own. The molecules bind to the protein channel, which changes shape to allow them to pass through, ultimately helping them move across the membrane.
Is aquaporin a channel protein?
Yes, aquaporin is a type of channel protein that facilitates the transport of water molecules across cell membranes.
What is the definition of protein gate?
A protein gate is a pathway through a protein molecule on the plasma membrane in which ions and small molecules can diffuse in or out of a cell.
Does facilitated diffusion require a carrier or channel protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion requires a carrier or channel protein for the movement of molecules across the cell membrane.
What is the structure and function of a beta barrel protein?
A beta barrel protein is a cylindrical structure made up of beta strands arranged in a barrel-like shape. This structure allows the protein to form a pore or channel that can transport molecules across cell membranes. The beta barrel protein's function is to facilitate the passage of specific molecules in and out of cells, serving as a gatekeeper for cellular processes.

What protein recognizes certain molecules bringing them across a membrane?
channel or transport or receptor
A junction that is a protein channel linking the cytoplasms of adjacent cells is called?
A junction that is a protein channel linking the cytoplasms of adjacent cells is called a gap junction. This structure allows for direct communication and sharing of ions and small molecules between neighboring cells.
