ACS Biochemistry EXAM QUESTIONS AND CORRECT DETAILED ANSWERS | EVERYTHING YOU NEED TO PASS Membrane lipids: phospholipids - ANSWER-Two classes: glycerophospholipids (aka phosphoglycerides) and sphingolipids. Both contain two non-polar tails, a platform they are linked to, and a phosphate-containing polar head group. Phosphoglycerides - ANSWER-class of phospholipids that have two fatty acid chains bound to the alcohol groups in glycerol, with the third alcohol group being bound to amino alcoho...

The amount of cholesterol in cell membranes varies from ~40% of lipids in the ______________ membrane to ~10% of lipids in the __________________ membranes correct answers The amount of cholesterol in cell membranes varies from ~40% of lipids in the plasma membrane to ~10% of lipids in the endoplasmic reticulum membranes What do high local concentrations of cholesterol do to phospholipids and membrane fluidity? correct answers prevent lateral movement of phospholipids and decrease membrane fl...

Three types of lipids in the cell membrane - Answer - Phospholipids - sphingolipids - cholesterol Phospholipids can arrange themselves as - Answer bilayer, Micelles (ball) or liposomes (ball with aqueous centre) Fluid mosaic model - Answer current cell membrane model, proteins dispersed, extracellular surface contains glycol lipids and proteins

What are sphingomyelins? - Sphingolipids where the head group is phosphocholine or phosphoethanolamine. What prevents cells from actually swelling? - It is effectively impossible for sodium to enter the cell (due to pump and lack of sodium channels). There is a high sodium ion concentration outside the cell which prevents water from entering in the cell Why would cells have a tendency to swell? - Because cytoplasm contains negatively charged proteins that cannot exit, so cells naturally ga...
