Any biological cell membrane or plasma membrane is made up of phospholipid bi-layer, cholesterol, small amounts of glycolipids and specialized proteins. Some components can move little bit around their position but others such as cholesterol add to the rigidity of the membrane. Lipid rafts are also immovable regions of the membrane.
No, neutralizing chemicals is not a function of cell membranes in a cell. Cell membranes primarily serve as a barrier, regulating the entry and exit of substances to maintain the cell's internal environment. Neutralizing chemicals is a function typically performed by enzymes or other molecules within the cell's cytoplasm.
phospholipids
A Golgi apparatus is a stack of membranes that packages chemicals, such as proteins and lipids, into vesicles for transport within the cell or for secretion outside the cell.
The cell's membrane separates the inside from the outside and allows certain chemicals to pass, others are kept out.
Ethanol/Alcohol, and alot of other harmful substances/chemicals.
Living systems have cell membranes that separate internal chemicals from the external chemical environment. These membranes control the movement of substances in and out of the cell, allowing for selective exchange of molecules and maintaining internal conditions necessary for life.
Cheetahs do not have cell walls. However, like all living organisms, they have cell membranes that surround and protect their cells. Cell membranes regulate the passage of substances in and out of the cell.
oxygen
Yes, protists have cell membranes. Cell membranes are present in all living cells, including those of protists, to regulate the passage of materials into and out of the cell and maintain cellular structure and function.
Calcium depolarizes cell membranes.
Plants have cell membranes just inside their cell walls. The cell membranes control what passes into and out of the cell.
Cell membranes act as a barrier, controlling the movement of substances in and out of the cell. They help maintain cell shape and provide support. Additionally, cell membranes are important for cell communication and recognition.
