What can't pass through the phospholipid bilayer?
Large molecules such as proteins, charged ions, and polar molecules have difficulty passing through the phospholipid bilayer due to its hydrophobic core. These molecules often require assistance from transport proteins or channels to facilitate their movement across the membrane.
What is the basic structure of the plasma membrane?
The plasma membrane is composed of a phospholipid bilayer with embedded proteins. The phospholipids have a hydrophilic head and hydrophobic tail, creating a barrier that controls the passage of substances in and out of the cell. The proteins within the membrane have various functions, such as transport, signal transduction, and cell recognition.
What are the specialized parts of a phospholipid bilayer?
The specialized parts of a phospholipid bilayer include the hydrophilic heads facing outward towards the aqueous environment and the hydrophobic tails facing inward, creating a barrier that prevents water-soluble molecules from passing through. Additionally, integral proteins can be embedded within the bilayer to facilitate transport and communication across the membrane.
Why do integral proteins stay in place in the phospholipid bilayer?
Integral proteins stay in place in the phospholipid bilayer due to hydrophobic interactions between the nonpolar regions of the protein and the hydrophobic fatty acid tails of the phospholipids. This interaction helps anchor the integral proteins within the bilayer, providing stability and allowing them to carry out their specific functions, such as cell signaling or transport of molecules across the membrane.
What are the specialized parts of the phospholipid bilayer?
The Phospholipid Bilayer is made up of phospholipids. These phospholipids have a hydrophillic head, and a hydrophobic tail. They are structured so that the hydrophillic head interacts with water, and the hydrophobic tails stays away from water, but mixes with fat. This makes the phospholipids form the phospholipid bilayer. The Phospholipid Bilayer has intrinsic proteins and extrinsic proteins attached, which may have glycoproteins attached to them. Glycolipids may also be attached to the hydrophillic heads of the phospholipid. Cholestrol is also part of the phospholipid bilayer, which adds strengh to the structure.
What concentration does active transport take place in?
the phospholipid bilayer of a cell

What is another name for the phospholipid bilayer?
It depends on which lipid bilayer you're talking about. There is the phospholipid bilayer that surrounds eukaryotic cells, cholesterol phospholipid bilayers, protein lipid bilayers, phase transition lipid bilayer, lipid bilayer membrane...

What is a basic structure of a cell membrane?
A cell membrane consists of a phospholipid bilayer with embedded proteins. The phospholipid bilayer is made up of two layers of phospholipid molecules, with hydrophilic heads facing outward and hydrophobic tails facing inward. The proteins in the membrane help to regulate transport of molecules in and out of the cell.

What Makes up the membrane of the cell?
Mainly a phospholipid bilayer, with transport proteins sandwiched in between. There are several diagrams on the internet and in Biology textbooks of this. A picture is worth a thousand words...

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.

Layers that make up the cell membrane?
The cell membrane is composed of a phospholipid bilayer, which consists of two layers of phospholipid molecules oriented with their hydrophilic heads facing outward and their hydrophobic tails facing inward. Embedded within this bilayer are proteins that perform various functions such as transport, signaling, and structural support. Additionally, cholesterol molecules are interspersed within the phospholipid bilayer to help maintain its fluidity and stability.
