BIO311C 1nd Edition Lecture 15 Outline of Last Lecture Active and Passive Transport Outline of Current Lecture Fluidity of the membrane Current LectureHigh amounts of oxygen gave rise to the aerobic bacteria which lead to the concept of aerobic respiration.Plasma membrane functions:Isolate cytoplasm from external environmentStructure: Semi permeable phospholipid bilayer which controls passage of moleculesDetermines characteristic of membranes Ratio of unsaturated to saturated fatty acids affect fluidity of the membrane As cholesterol increases, the fluidity of the membrane increases. Membrane carbs: Glycoproteins Membrane proteins: Peripheral, integral, trans-membrane Membrane gives direction Temperature of the membrane increases, percentage of cells with mixed proteins increases, fluidity increases. Fluidity is affected by the membrane components These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a
