Document Summary
Binding change mechanism: gamma subunit rotating to change conformation of betta subunit. Problem with movie: shows single channel when it is actually a half-channel. Aerobic information summary slide: proton-motive force is used to bring inorganic phosphate into the membrane (new info) Many membranes inside the cell that divide it into compartments. Compartments are not independent- they form an integrated functional unit. All membranes are interdependent (part of endomembrane system) All of these are part of biosynthetic pathway: synthesis and sorting + secretion. Specialized cells in adrenal glands or gonads have lots of ser. N-linked: added to asparagine (sugar added is n-acetyl. O-linked (less frequent) : added to (sugar added. Glycosyltransferase are enzymes that add sugars to growing sugar tree. Dolichol is a special type of lipid in er membrane: acts as conveyor belt. Uggt monitoring enzyme recognizes proteins that are not properly folded by identifying hydrophobic amino acids pointing to the outside (should be pointing inside)
