The bulk of cellular membranes are made of lipids, which keep materials from moving in either direction, while there are proteins stuck in at irregular intervals that selectively allow materials to move in and out.
Hydrogen carbon, and some oxygen. I think it has h20, and amino acids and proteins.
The nucleus of a cell contains primarily DNA molecules. It also has RNA and ribosomes as well as smaller molecules like the ubiquitous water, glucose, oxygen and salts.
proteins and phospholipids make up most of the cell membrane
The cell membrane is a part of a cell; specifically, it is the outermost layer, or effectively the skin of the cell. It is not made up of cells. A cell is not itself made up of cells, that would entail an infinite regression.
The cell membrane, or phospholipid bylayer.
yes
cell wall (which is made up of cellulose, which is made up of beta glucose)
Plant cells are enclosed by a cell membrane and cell wall. The cell wall is a rigid structure made up of cellulose and the cell membrane is a semipermeable membrane made up of protein and fat.
Cell membrane pores are made up of protein.
The cell membrane is made up of a bilayer of phospholipids.
phospholipid bilayer
The cell membrane is a part of a cell; specifically, it is the outermost layer, or effectively the skin of the cell. It is not made up of cells. A cell is not itself made up of cells, that would entail an infinite regression.
The cell membrane's bilayer structure is made up of phospholipids.
phospholipids
The cell membrane, or phospholipid bylayer.
The cell membrane is made up of phospholipids; hydrophobic and hydrophilic. The cell is only in plant cells and is made of cellulose.
turtles
yes
cell wall (which is made up of cellulose, which is made up of beta glucose)
The membrane of a cell is basically made up of a mixture of lipids and proteins. The other components of a membrane of a cell are phospholipids and glycoproteins.
