Most structures consist of a phospholipid bi-layer although that term is mostly associated with the cell wall in my experience. other structures such as the rough and smooth Endoplasmic Reticulum also use phospholipid bi-layers to partian themselves from the rest of the cell.
What else can I help you with?
What is the key structural element of a cell membrane?
The primary structural component of a cell membrane is the phospholid layers. This is mainly made of proteins which facilitate various cell activities.
Where are phospholipids primarily found in the body?
The main component of cell membranes are made up of phospholipids. In fact, another name for the cell membrane is the phospholipid bilayer.
What element are stars mostly composed of?
hydrogen,All stars are composed primarily of hydrogen. Stars can also contain some other elements such as helium, but hydrogen accounts for the majority of a star's composition.
Who discovered that electrons move in empty space in an atom?
It was Ernest Rutherford who discovered that atoms are mostly composed of empty space with electrons orbiting a very dense nucleus.
What does geosphere mean in science term?
The term geosphere is often used to refer to the densest parts of Earth, which consist mostly of rock
What is the cell membrane's composed of?
composed of a phospholipid bilayer, which has 2 layers of phospholipids back-to-back
Do lipid molecules need phospholipid translocators to pass through cell membrane?
Lipid molecules are what make up the cellular membrane. Lipids are mostly composed of phospholipids creating a phospholipid bilayer. Each phospholipid has a polar head and a non polar tail. There are two layers of phospholipids composing the bilayer with non polar tails facing towards eachother. Each layer is known as a leaflet. The phospholipid translocators are designated to 'flip-flop' the phospholipids between each leaflet to increase fluidity of the membrane.
What is the landmass called that mainly consists of jungle?
South America is the landmass that consists mostly of jungle.
Which type of molecule is found in the plasma membrane?
The plasma membrane is composed mostly of phospholipids
What is the key structural element of a cell membrane?
The primary structural component of a cell membrane is the phospholid layers. This is mainly made of proteins which facilitate various cell activities.
Is the cell wall composed of lipids?
The cell membrane is made of phospholipids.The plant cell wall is mostly composed of cellulose, the fungal cell wall of chitin and the algal cell wall of a polysaccharide (like cellulose) or a glycoprotein.
What is the protective outer covering of a cell that regulate the interaction between the cell and the environment?
Its the cell membrane (or plasma membrane), composed of phospholipid bilayer ,membrane proteins and cholesterol in eukaryotes. the regulation is largely by way of signalling molecules that interact with specefic receptors on the membrane (mostly proteins or glycoproteins). hope that helps Dr. David
How is crust related to crystal?
The crust is largely composed of rocks, which are mostly composed of minerals, which have a crystalline structure.
What mostly make up the cell membranes?
Cell membranes are made up of proteins called PHOSPHOLIPID BILAYER It has phosphate molecules attached to the proteins There is also CHOLESTEROL in the cell membrane to make it more fluid
Describe how phospholipid molecules are oriented in the plasma membrane of a cell?
The plasma membrane and other membranes of a cell are composed mostly of proteins and a type of lipid called phospholipids. A phospholipids molecule is structured with two fatty acids. The two fatty acids at one end (the tail) of the phospholipids are hydrophobic (not attracted to water). The other end (the head) of the molecule includes a phosphate group, which is negatively charged and hydrophilic (attracted to water). Thus, the tail end of a phospholipids is pushed away by water, while the head is attracted to water.
What polysaccharides is used for cell walls?
The primary structure of the cell wall is mostly cellulose while the secondary structure is composed of lignin.
What types molecules are present in cell membrane?
The cell membrane is composed of different kinds of molecules. The phospholipid chains surround the cell and is what the cell membrane is primarily made of. Around the cell, you can also find proteins embedded on or all the way through the cell. This protein helps large molecules from outside the cell or inside the cell to go in or out. Between the phospholipid is also cholesterol which helps the cell membrane fluidity. This all being said, there are three things that make up the cell membrane: # The phospholipid bilayer # The protein inside and outside the cell # cholesterol between some phospholipid chains.
