How do carrier protiens transport substances across cell membrane?
Carrier proteins facilitate the transport of substances across the cell membrane by binding to the specific molecules they transport and undergoing conformational changes to move the molecules across the membrane. This process is often referred to as facilitated diffusion. It allows for the transport of specific molecules, such as glucose or ions, across the membrane, down their 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.
Is the flexible nature of a cell membrane results from its channel proteins true?
Yes, the flexible nature of a cell membrane results from its phospholipid bilayer, which allows for movement and bending. Channel proteins, on the other hand, facilitate the transport of specific molecules across the membrane but do not contribute significantly to the overall flexibility of the membrane.
How do you transport proteins in a cell make it easier for certain molecules to diffuse across a membrane?
Proteins in the cell membrane can act as transporters or channels, aiding in the facilitated diffusion of specific molecules across the membrane. These proteins provide a passageway for the molecules to move across the membrane by utilizing their specific structure and function. This process helps regulate the movement of molecules in and out of the cell.
Yard is to fence as cell is to?
Yard is to fence as cell is to membrane. Just like a fence surrounds a yard and allows certain objects in and out, a membrane surrounds the cell and only allows specific nutrients inside of it.

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.
Are carrier proteins specific in their action?
Yes, carrier proteins are specific in their action. They selectively bind and transport only certain molecules or ions across a cell membrane or within a cell, based on their shape and properties. This specificity allows cells to regulate the movement of substances in and out of the cell with a high degree of control.
Which part of a cell allows substances to pass through it?
The cell membrane, specifically its lipid bilayer, regulates the passage of substances into and out of the cell through a process called selective permeability. Various proteins embedded in the membrane also assist in facilitating the movement of specific molecules across the membrane.
What cell component controls entry and exit of materials into and out of the cell and state how it controls this?
The cell membrane, or plasma membrane, controls the entry and exit of materials into and out of the cell. This is done through selective permeability, which allows the membrane to regulate the passage of substances based on factors such as size, charge, and solubility. Transport proteins embedded in the membrane also play a key role in facilitating the movement of specific molecules across the membrane.
Is the flexible nature of a cell membrane results from its channel proteins true?
Yes, the flexible nature of a cell membrane results from its phospholipid bilayer, which allows for movement and bending. Channel proteins, on the other hand, facilitate the transport of specific molecules across the membrane but do not contribute significantly to the overall flexibility of the membrane.
Which part allows or prevents substances to go into and out of the cell?
The cell membrane acts as the barrier and transport proteins present in the membrane, such as globular proteins, transport molecules across cell membranes.
Is the plasma membrane of a cell selectively permeable?
Yes, it is selective about the compounds and molecules it allows across the membrane.

What are membrane proteins that create a passageway across cell membrane?
These are called channel proteins, which facilitate the passage of specific ions or molecules across the cell membrane. They can be gated or non-gated, and their structure is such that they form a tunnel through which substances can move in or out of the cell.
