Cell Membrane
Cards in this deck (12)
- 1Name the components of a cell membrane1. Phospholipid Bilayer
2. Transmembrane Proteins
3. Interior Cell Network
4. Cell Surface Markers - 2Phospholipid Bilayer- made of phospholipids
- only allows small non-polar molecules through
- does not allow other molecules into the interior of bilayer and cell - 3Name the 3 transmembrane proteins1. Carriers
2. Receptors
3. Channels - 4Carriers (What it is + function)- TRANSMEMBRANE PROTEIN
- actively or passively transports molecules across membrane
- uses a series of conformational changes
(e.g. sodium potassium pump) - 5Channels (What it is + function)TRANSMEMBRANE PROTEIN
- passively transports molecules across membrane by creating a tunnel that acts as a passage
(e.g. sodium-potassium channels in heart, nerve, and muscle cells) - 6Receptors (What it is + function)TRANSMEMBRANE PROTEIN
- transmits information and signals between the interior and exterior areas of the cell
(e.g. receptors that bind peptide hormones and neurotransmitters) - 7Name the 2 components of the Interior Protein Network1. Spectrins
2. Clathrins - 8Spectrin (What it is + function)part of INTERIOR PROTEIN NETWORK
- determines shape of cell
- forms a scaffolding that attaches to cytoskeleton and membrane
(e.g. red blood cell) - 9Clathrin (What it is + function)part of INTERIOR PROTEIN NETWORK
- anchor different proteins to specific sites on the exterior of membrane in receptor-mediated endocytosis
- proteins bind coated pit and help binding to specific molecules - 10Name the 2 cell surface markers1. Glycoproteins
Glycolipids - 11Glycoproteins (What they are + function)Are CELL SURFACE MARKERS
- helps with self-recognition
- important in white-blood cell recognition and the immune system
- creates a carbohydrate/protein chain that is characteristic of the individual
(e.g. Major histocompatibility complex proteins) - 12Glycolipids (What they are + function)Are CELL SURFACE MARKERS
- helps with tissue recognition
creates a lipid/carbohydrate chain that is characteristic of the tissue
(e.g. A,B, and O blood group markers)
