phospholipids
Most membrane functions are carried out by proteins. The cell membrane is important because it protects what is inside the cell from outside damage.
the phospholipids. by weight it is half protein and half lipid
The cell membrane. It is a lipid bilayer with proteins integrated into it for transportation into and out of the cell.
Either the cell membrane, or the cell wall. The cell membrane is most common in animals, and protists, whereas some monerans, and most plants and fungi have a cell wall.
cell membrane (cell wall), nucleus, centrosome, protoplasm, and nuclear membrane these are the main parts...as for just 3, i guess you can pick The 3 basic cell parts are: 1. Plasma Membrane- The outer boundary of the cell. It controls what enters and exits the cell. 2. Cytoplasm- Portion of cell outside of the nucleus; is a semi-fluid cytosol with imbedded organelles. 3. A Control Center- Contains the DNA and controlls cell activities. In most cells this is a nucleus but not all.
the outer membrane
Most membrane functions are carried out by proteins. The cell membrane is important because it protects what is inside the cell from outside damage.
hormones
For most eukaryotic organisms it is dipalitoylphosphatidylcholine (DPPC), a phospholipid.
a nucleus, the cytoplasm, and cell membrane
the phospholipids. by weight it is half protein and half lipid
The cell membrane. It is a lipid bilayer with proteins integrated into it for transportation into and out of the cell.
cell membrane is the most outer part of a cell. cell membrane is very big in surface.
The primary structural component of a cell membrane is the phospholid layers. This is mainly made of proteins which facilitate various cell activities.
Either the cell membrane, or the cell wall. The cell membrane is most common in animals, and protists, whereas some monerans, and most plants and fungi have a cell wall.
Cells have methods other than diffusion/osmosis to move materials across the cell membrane, most of which involve membrane proteins and require the use of energy. The cell membrane also performs functions other than controlling the movement of materials into and out of the cell, and the membranes of some specialized cells have very complex functions. So we can see that the cell membrane is a very intricate and important component of the cell.
Most receptors are located in the outer cell membrane.
