How does the structure of a phospholipid molecule contribute to the way such molecules are organized in a cellular membrane?

I think that we must have the same textbook because I had the same exact answer. What I found on page 115 was that in each phospholipid molecule, there is a head which is hydrophilic (loves water) and the tails of the molecule are hydrophobic (hate water). The structure allows them to form boundaries between two watery environments. The membrane is a phospholipid bilayer and what happens is that the hydrophilic heads are facing the water, while the tails are on the other side meeting other tails, and the heads are duplicated on the bottom.

∙ 12y agoWith the hydophillic phosphate head dissolving in solution and the hydrophobic lipid tails being insoluble and seeking to stay away from water the structure, micelles, comes about rather naturally with no input of anabolic energy.

What 2 fat-based molecules make up part of the structure of the plasma membrane?
phospholipid and cholesterol
How is membrane structure related to the transport of materials?
Membrane is thin and Êsemi permeable to allow Êmaterials to enter and exit easily. In addition, it Êconsist Êof protein Êand phospholipid bilayer, Êprotein layer release ÊproteinÊÊmolecules which act as carriers across the membrane.Ê Whereas, phospholipid bilayer Êallow small molecules such as water molecules to pass through quicker.
What is the thin layer around the cell that acts like a gate for the cell?
The cell wall. This structure is made up of a phospholipid bilayer and is studded with transport proteins that help pump molecules in and out of the cell. Many molecules are small enough to pass through the cell wall unaided by these proteins.
What is the purpose of a structure?
Organized.
What molecules can pass phospholipid bilayer?
Non ionized molecule pass through the lipid bilayer faster than ionized molecules because of the hydrophobic portion of the lipid bilayer. non ionized molecules are ex glucose ionized molecute Na, K
What is the basic structure of the plasma membrane?
The framework of the cell membrane is formed by the lipid bilayer. The lipid bilayer is composed of two layers of fat cells organized in two sheets. This is what provides the barrier that makes the boundaries of the cell.
What are molecules that are joined in an ordered structure?
When molecules are linked in organized positions has solid results. When heat is absorbed by a solid the molecules vibrate faster and faster.
How does the structure of phospholipids linear molecules with a polar end and a nonpolar end relate to their function in the cell membrane?
Which is the effect of having the polar and nonpolar ends of phospholipid molecules oriented as they are in this illustration?
What 2 fat-based molecules make up part of the structure of the plasma membrane?
phospholipid and cholesterol
What is the Main structural component of a plasma membrane?
The basic structure of all membranes is the same. They are composed of two layers of phospholipid molecules, associated with other molecules including proteins, carbohydrates and cholesterol. I hope this helps.
General structure of cell membrane?
A phospholipid bilayer.
What is the phospholipids structure?
The general structure of a phospholipid is composed of a hydrophilic head and a hydrophobic tail.
What is the structure of phospholipids?
The general structure of a phospholipid is composed of a hydrophilic head and a hydrophobic tail.
Why is the structure of a phospholipid so important to the cell?
They are selectively permeable, provides structure to cells.
How is membrane structure related to the transport of materials?
Membrane is thin and Êsemi permeable to allow Êmaterials to enter and exit easily. In addition, it Êconsist Êof protein Êand phospholipid bilayer, Êprotein layer release ÊproteinÊÊmolecules which act as carriers across the membrane.Ê Whereas, phospholipid bilayer Êallow small molecules such as water molecules to pass through quicker.
What structure in living organisms is made of a phospholipid'?
the cell membrane
What function do carbohydrate portions of molecules perform?
The functions of carbohydrate portions of molecules include energy storage. It also functions as the backbone of RNA and DNA molecules. Carbohydrates also contribute to the structure of cell walls.
