Unsaturated Fats Case Study

5. How can you distinguish between a saturated fat and an unsaturated fat at the molecular level?
Saturated and unsaturated fats differ in their chemical structures. Saturated fats have no double bond between molecules, which means there are no gaps and the fat is saturated with hydrogen molecules. On the other hand, unsaturated fats have double bonds, which break up the chain of hydrogen molecules and create gaps, allowing the fats to liquefy at room temperature.
Describe the process of facilitated diffusion and active transport
Facilitated diffusion is a process of transportation of molecules across cell membrane form an area of high concentration to an area of low transportation through protein channels
Active transport is when a protein moves a certain material across the membrane from a region of lower concentration to a region of higher concentration against the concentration gradient using energy. 6. How do large molecules, such as proteins, get into a cell?

The electrons come from water molecules, and the energy is first absorbed by pigments known as chlorophylls and carotenoids. The former absorb blue and red light and the later absorb blue-green light. Green and yellow light are not absorbed. Reflections of these types of light make plants appear green. There are many varieties of pigments. They are bonded to proteins which provide pigment molecules with the appropriate orientation and position with respect to each other. After absorption by pigment, light energy is transferred to chlorophylls that are bonded to special proteins. Pigments and protein involved with this actual primary electron transfer event together are called the reaction center. A large number of pigment molecules, collectively referred to as antenna, "harvest" light and transfer the light energy to the I same reaction center. The purpose is to maintain a high rate of electron transfer in the reaction center, even at lower light
