Document Summary
Form the semipermeable barrier around the cell interior. Some phospholipid constituents may be integral to cell signaling ie. phosphatidylserine ips the outer leaf during certain forms of cell death and may signal this change to other cells: membrane proteins: Anchors for cytoskeletal elements and extracellular matrix components. Transport of hydrophilic substances across the membrane. Ribosomes are the site of protein synthesis. Extract energy from nutrients and oxygen and synthesize atp. In the resting state (interphase) dna can be recognized as chromatin, prior to reproduction the chromatin coils into chromosomes. Contains chemicals, facilitating chemical reactions: ions. Necessary for cellular reactions and may act as control mechanisms on cell membranes: proteins. Globular proteins have enzymatic functions: lipids. Most abundant type is neutral fat (triglycerides: carbs. Hemolympathic (comprise immune systems, in ammatory cells and blood) As cells undergo stresses they have adaptive responses. When the adaptive ability of the cell is exceeded then cell injury develops.
