Lipid raft - Study guides, Class notes & Summaries

Cholesterol in the plasma membrane can gather together to form a _______ lipid raft What's the purpose of the folding of the inner membrane crustal? to increase surface area This organelle has a role for assembling polypeptides A. Golgi apparatus B. Ribosomes C. Nucleus b. Ribosomes In erad, what's the target protein and what attaches onto the target protein? target protein = badly folded protein Ubiquitin T or f: the free aa that's generated from erad can't be reused f; they can be reu...

Phospholipid bilayer the basic framework of a biological membrane, consisting of two layers of phospholipids. Fluid mosaic model the accepted model of a biological membrane; its basic framework is the semifluid phospholipid bilayer with a mosaic of proteins. Carbohydrates may be attached to the lipids or proteins. Leaflet 1. Half of a phospholipid bilayer. 2. A portion of a compound leaf. Transmembrane proteins a protein that has one or more regions that are physically embedded in the hydroph...

CNS - ANSWERSWhere is pain perceived, neurons in the CNS or PNS? myoglobin - ANSWERSWhat is a substance that holds oxygen in muscles and organs? mRNA - ANSWERSThe destruction of what prevents continuous protein production - that allows the cell to change its protein expression over time? timing - ANSWERSWhat about the expression of an antisense gene is a key featu...

BIOL/CHEM 3362 - BIOCHEMISTRY II EXAM 3 STUDY GUIDE 1. How are the chiral carbons on the glycerol of the trigycerides determined? C1 is the carbon that would lead to S-configuration if its priority was increased. (chapter 8 slide 44) 2. How are the archaeal membrane lipids different from membrane lipids found in bacteria and eukaryotes? They are connected to the enantiomers of the bacteria and eukaryotes glycerol. (chapter 8 slide 49-50), Archaea vs bacteria:snG1P vs snG3P (enantiomers). Bacteri...

be differences in the "sides" of a cell when we talk about cellular polarity. (3pts) The membranes of cells also show "polarity". Name at least 3 separate characteristics of the membrane in the image below that illustrate polarity 1. Chol 0 Gang SPM OPI TM1 TM2 Acyl cytoplasm 2. (3pts) The blue shaded regions of the membrane are lipid rafts, which show differences in lipid and protein composition from other parts of the membrane. These differences restrict movement of molecules ...

summary of the plasma membrane with information on composition, function, and processes it is involved. Information regarding protein channels, pumps, electron gradient, endocytosis, and exocytosis.
