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?
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.*This is from Wikipedia.....
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?
Carrier molecules are molecules that play a role in transporting electrons through the electron transport chain. Carrier molecules are usually proteins bound to a nonprotein group; they can undergo oxidation and reduction relatively easily, thus allowing electrons to flow through the system. There are four types of carrier: flavoproteins (e.g. FAD), cytochromes, iron-sulphur proteins (e.g. ferredoxin), and ubiquinone.
What cell part deals with Diffusion osmosis and active transport?
The cell membrane, specifically the phospholipid bilayer, is responsible for facilitating diffusion, osmosis, and active transport of molecules in and out of the cell. Various proteins, such as ion channels and pumps, play a role in active transport processes by assisting in the movement of specific molecules against their concentration gradients.

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.

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 organelle similar to diffusion?
The organelle similar to diffusion is the cell membrane, which regulates the movement of substances in and out of the cell. It allows small molecules and ions to pass through via simple diffusion, balancing concentrations inside and outside the cell. Additionally, the membrane contains proteins that facilitate facilitated diffusion, helping larger or polar molecules cross more efficiently. Thus, the cell membrane plays a crucial role in maintaining homeostasis through diffusion-like processes.
What role do carrier protiens play in facilitated diffusion?
facilitated diffusion is also called cell-mediated diffusion because a substance transport in this manner diffuses through the membrane using a specific carrier protein to help.first, carrier protein binds to the binding site of the carrier protein ,and then there is a conformational change in the shape of the carrier protein that helps the molecule to diffuse other side of the membrane.
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
