1. Explain why phosphoglycerides are found in lipid bilayer 2. Enumerate and describe the mechanisms of transport across a membrane
In the cell membrane bilayer: most of the lipids have an inverted cone shape (headgroup region wider than the tail region on a lipid). 3 of these 4 responses are correct the hydrophobic lipid region is situated between the hydrophilic lipid regions. negatively-charged lipids are located mainly in the outer leaflet of the bilayer. O cholesterol always works to make membranes more fluid, regardless of the circumstances.
1. Flip-Flop is considered the LEAST likely to happen of the four membrane movements because it is the LEAST energetically favorable movement of a single fatty acid. For this question DRAW the action of a one phopholipid being flipped from outside facing plasma membrane, to the inside facing plasma membrane. On your drawing put an X near areas of the phospholipids that do NOT want to interact during this process.
6) Pore-forming toxins are a class of protein-based toxic polymers that result in the formation of large multi-protein channels that allow the free flow of substrates and liquid in and out of a cell or organelle. Research shows that these can attach to the outer mitochondrial membrane, or on the thylakoid membranes Hollyal of chloroplasts.
