Document Summary
*homework quiz 24 hours before each class ends when class begins. *doc called outcomes posted on webct what you are expected to know. Oil is a non-polar hydrocarbon, insoluble in water. Molecules with higher en will be more closely attracted to each other. Look at the third major ingredient (eggs) they contain molecules that are amphiphilic (have both hydrophobic and hydrophilic regions) Eggs provide phospholipids, which contain polar and non-polar parts. Phospholipids assemble into bilayer when added to an aqueous liquid hydrophobic fatty acids aggregate while polar head groups associate with water. Mayo and the origin of life membranes are formed by phospholipid bilayers, which contain both hydrophobic and hydrophilic portions. Comparing types of membrane transport pg. By acting as a selectively permeable barrier, the plasma membrane allows for nutrient uptake and waste elimination while maintaining a protected environment in which metabolic processes can occur. Fluid mosaic model says membrane is fluid and asymmetrical.
