plasma membrane of animal cells is made up of phospholipid bilayer.It contains phospholipid molecules,globular proteins,cholesterol,carbohydrates etc.model of the plasma membr…ane is known as the fluid mosaic model. I am an integrative healthcare professional, massage therapist, and health sciences educator. Cell membrane. The cell membrane (also known as the plasma membrane or cytoplasmic membrane) is a biological membrane that separates the interior of all cells from the outside environment. The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. Rating Newest Oldest. Best Answer: The sarcolemma is the cell membrane of a muscle cell. It consists of a true cell membrane, called the plasma membrane, and an outer coat made up of a thin layer of polysaccharide material that contains numerous thin collagen fibrils. Phospholipid bi-layer or Plasma Membrane. The reason why Cell membrane can be called Phospholipid bilayer is because, membrane in animal cells are made of those. A phospholipid bilayer is made of an hydrophilic (likes water) head, which is a phosphate. And a hydrophobic tail (hates water) made of a fats chain. Because the membrane is situated between two liquid (cell cytoplasm and extracellular fluid) it form a bilayer in order to protect his hydrophobic tails from the liquid. There are two basic types of transmembrane proteins: alpha-helical and beta-barrels. Alpha-helical proteins are present in the inner membranes of bacterial cells or the plasma membrane of eukaryotes, and sometimes in the outer membranes. This is the major category of transmembrane proteins. In humans, 27% of all proteins have been estimated to be alpha-helical membrane proteins. sarcolemma The sarcolemma is the cell membrane of a muscle cell. It consists of a true cell membrane, called the plasma membrane, and an outer coat made up of a thin layer of polysaccharide material that contains numerous thin collagen fibrils.. Ann · 1 year ago. Word Origin & History. membrane 1510s, parchment, from L. membrana parchment, from membrum limb, member of the body (see member). Meaning thin layer of skin, tissue covering a limb or organ is attested from c.1600. The plasma membrane is another name for the cell membrane. It encloses the organelles & the intracellular fluid & keeps them separate from the extracellular environment, but s…electively allows substances to pass through in either direction. Plasma membrane- The membrane enclosing a cell is made up of two lipid layers called a bilipid membrane. The lipids that are present in the plasma membrane are called phospholipids.. These lipid layers are made up of a number of fatty acid building blocks. Word Origin & History. membrane 1510s, parchment, from L. membrana parchment, from membrum limb, member of the body (see member). The etymological sense is that which covers the members of the body.. Meaning thin layer of skin, tissue covering a limb or organ is attested from c.1600.
