Proteins play a role in facilitated diffusion by acting as channels or carriers that help specific molecules pass through the cell membrane. These proteins facilitate the movement of molecules that are too large or polar to pass through the membrane on their own.

Transport proteins play a role in both?
Transport proteins play a critical role in facilitating the movement of molecules across biological membranes, such as ions, nutrients, and waste products. They help maintain cellular homeostasis by regulating the flow of substances into and out of the cell. Transport proteins can be passive (facilitated diffusion) or active (requiring energy).
How do transport proteins move substances across membranes?
Transport proteins facilitate the movement of substances across membranes through processes like facilitated diffusion and active transport. These proteins have specific binding sites that recognize and transport specific molecules or ions across the lipid bilayer. Depending on the transport protein, the movement can be passive (down a concentration gradient) or active (against a concentration gradient, requiring energy).
What is embedded in the phospholipid bilayer that also aid in diffusion and in the cell recognition?
Proteins are embedded in the phospholipid bilayer that help in facilitating the movement of molecules across the membrane and also play a role in cell recognition processes. These proteins may function as channels for specific molecules, receptors for signaling molecules, or transporters for ions.
What occurs when substances move against the concentration gradient requires and the aid of carrier proteins?
This process is called active transport, where energy is needed to move substances against their concentration gradient. Carrier proteins use ATP to pump molecules or ions across the cell membrane, creating a concentration gradient. This process allows cells to maintain proper internal conditions.
What is the role of proteins in living things?
Proteins play various essential roles in living things, acting as enzymes to facilitate chemical reactions, transporting molecules within cells, providing structural support to cells and tissues, and serving as signaling molecules for communication between cells. Proteins also play a crucial role in the immune system, acting as antibodies to recognize and neutralize harmful pathogens.

What aids in diffusion and in cell recognition?
Proteins play a key role in aiding diffusion across cell membranes by acting as channels or carriers. Cell recognition is facilitated by cell surface markers such as glycoproteins and glycolipids, which help cells identify and communicate with each other.
Diffusion and facilitated diffusion?
Diffusion:Diffusion describes the spread of particles through random motion from regions of higher concentration to regions of lower concentration. The time dependence of the statistical distribution in space is given by the diffusion equation. The concept of diffusion is tied to that of mass transfer driven by a concentration gradient, but diffusion can still occur when there is no concentration gradient (but there will be no net flux). diffusion is invoked in the social sciences to describe the spread of ideas.Facilitated diffusion:Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is a process of passive transport, facilitated by integral proteins. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane integral proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism
What role do carrier protein play in facilitated diffusion?
it moves large molecules or molecules that are not soluble in lipids across across the cell membrane. (Pg. 101 in science book...1st para.)
How does size play a role in diffusion?
no answer.
What is the difference int eh function of the proteins and the carbohydrates attached to a cell membrane?
Carbohydrates are not found separately in the membranes, they are always attached to proteins. Their usual role is to act as receptors or antigens. Proteins do a variety of things, mainly conducting the numerous types of membrane transport mechanisms: facilitated diffusion, channel proteins, etc. They can also act as anchors for extra- and intracellular skeletons.
What role does diffusion play?
it plays the cool side
What role do carrier protiens play in facilitated diffusion?
Carrier proteins in facilitated diffusion help transport specific molecules across the cell membrane by binding to the molecule on one side of the membrane, undergoing a conformational change, and releasing the molecule on the other side. They do not require energy input and facilitate the movement of specific molecules down their concentration gradient.
How do proteins play a role in human blood?
nutrients
What role does diffusion play in cellular respiration?
well ask yourself what does diffusion mean and compare it to cellular respiration and photosynthesis
What role do chromosomes play when a cell make proteins?
They contain the information to make the proteins.
