Due to asymmetrical distribution of lipids, these are the names of the lipids located on the inside surface of the cell.
This is the name of number 4.
In the fluid mosaic model of biological membranes, this is the action shown by number 1.
In the fluid mosaic model of biological membranes, this is the action shown by number 2, which rarely occurs without an enzyme.
In the fluid mosaic model of biological membranes, this is the action shown by number 3.
In the fluid mosaic model of biological membranes, this is the action shown by number 4.
Located on the outside of the cell, this lipid is important in the immune response. It is responsible for stimulation of apoptosis/ engulfment by macrophages and activates platelets during blood coagulation.
This lipid is located on the external face of the cell to provide mechanisms for immune recognition and surveillance.
This lipid is present on the cytoplasmic face of the PM in order aid in signalling pathways.
Flippase, Floppase, Scramblase, ER Flippase
These enzymes are responsible for catalyzing a flip-flop of phospholipids.
Flippase and Floppase
These enzymes are ATP-dependent.
These characteristics define this form of asymmetry in membranes.
Thinking about the name "Lipid Raft", one could expect this type of movement as defined in the fluid mosaic model.
Different membranes have different membrane:protein ratios. Number one represents this type of membrane, which has the highest lipid component.
Different membranes have different membrane:protein ratios. Number two represents this type of membrane, which has the highest protein component.
These are the 6 major functions of the membrane proteins.
This membrane protein can be removed only by agents that disrupt membrane structure, e.g. detergents
This membrane protein can be removed by agents that do not disrupt membrane structure. e.g. ETDA, high salt, base
These are involved with protein interactions with the membrane bilayer.
Single alpha helix and lipid (fatty acyl) anchor
Rolled up beta sheet
amphiphilic alpha helix
Lipid anchor (acyl or prenyl)
Oligosaccharide linker with lipid anchor
intra- and extra-cellular peripherally associated proteins (two numbers)
These modifications only occur on the protein sequences present on the extracellular surface of the final folded protein.
This is the major glycoprotein in the RBC membrane.
Looking at this hydropathy plot, this is the likely amino acid number location of a transmembrane domain. (use a range with interval of 20)
The transmembrane segment should include primarily this type of amino acid.
glycosylation sites are located in this part of the cell.
This picture shows the components of this type of cell.
Hereditary spherocytosis is caused by mutations in spectrin alpha chain, spectrin beta chain, ankyrin chain, and band 4.2. Hereditary elliptocytosis has the same mutations except in ankyrin. These proteins are located where in the cell.
The rounded shape of red cells makes it difficult for them to pass through the spleen without rupturing. This disease is characterized by hemolytic anemia, jaundice, gall stones, possible premature death. Treatment is to take out the spleen.
Bacteriorhodopsin is a protein with this many transmembrane alpha-helices.
Bacteriorhodopsin (pumps protons out of the cell)
This transmembrane protein found in the kingdom Archaea is known as this name and (has this function). Its function is coupled with ATP synthase.
Cytochrome c oxidase
This transmembrane protein is: - Located in the inner mitochondrial membrane - Couples e transfer to proton pumping, with 4 H to intermembrane space/ O2-->H2O - Has 3 subunits (mostly alpha helices) encoded by the mitochondrial genome
