Cell Membrane Flashcards
What components of the cell membrane contribute to the fluid quality of the cell membrane?
phospholipid bilayer, cholesterol, integral proteins
What experiment provided results that proteins drift throughout membrane?
markers were put on both a mouse and human cell and the cells were fused
What does a warm temperature do about the role of cholesterol within a cell?
restrains movement of phospholipids and decreases fluidity
What does a cool temperature do about the role of cholesterol within a cell?
prevents close packing, and maintains fluidity
How is winter wheat able to survive the cold temperatures of winter without serious cell damage?
% of unsaturated phospholipids increase in the fall and keeps the membrane from solidifying
What role do carbohydrates play on the surface of cell membranes?
Cell to cell recogniton
What is a glycoprotein?
a carbohydrate covalently bonded to a protein
What is a glycolipid?
a carbohydrate covalently bonded to a lipid
