Learning Objectives. outline the roles of membranes within cells and at the surface of cells. state that plasma (cell surface) membranes are partially permeable barriers. describe, with the aid of diagrams, the fluid mosaic model of membrane structure. UNIT III:. Lipid Metabolism. Part 3. Prostaglandins. , and the related compounds . thromboxanes. and leukotrienes, are collectively known as eicosanoids to reflect their origin from polyunsaturated fatty acids with 20 . Group 2- Cell Development. Gladys Alexandre, Cristina Calestani, John Koontz, Silvia Moreno, Brian Ring, William Said. Context: Principles of Biology I (BIOL 1107); >250 students (freshman level). Essential idea: The structure of biological membranes makes them fluid and dynamic.. Above . are models of a plasma membrane showing how it's fluidity allows lipid soluble molecules to move directly through the membrane.. Team members: . Heather .

Confluent cultures cells were prelabeled prelabeled 1-"Clarachi What is the plasma membrane?. A flexible boundary between the cell and its environment which maintains . HOMEOSTASIS. within the cell. **Remember that . HOMEOSTASIS. is a state of balance/equilibrium within the cell.. Eicosanoids. Several Classes of Signal Molecules:. . P. rosta. g. landins, Thromboxanes, Leukotrienes. Produced In Almost all Tissues. Wide Range of Responses. Local Hormones. Very Potent. Short Half Life . The plasma membrane is a SELECTIVELY PERMEABLE membrane that allows nutrients and wastes to enter and exit the cell. Homeostasis: maintaining balance in the cell. The Plasma Membrane. Selective Permeability – allows some molecules to pass through and keeps others out. Compound Lipids. Compound lipids are . class of Lipids . C. hemically .

Module 1: Components a nd Architecture o f Cell Membrane Learning objectives: In this module, prime focus is mainly on the plasma membrane, however, majority of the concepts discussed below are also . Images from transmission electron microscopy were less conclusive but improvement can be done in future by use of antibodies to visualize FLAP nanodiscs. Ultimately, reconstitution of FLAP was succe are neutral fats. They are composed of a central . glycerol group . (C. 3. O. 3. H. 3. ) that can attach to three . fatty acids tails . (long strands of carbon and hydrogen). Attaching a fatty acid tail to a glycerol group produces a water molecule and is called a .
