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?
Large molecules such as proteins get into a cell through a process called ENDOCYTOSIS. inthis process a portion of the inward-facing surface of the plasma membrane becomes coated with a protein called clathrin, which stabilizes this section of the membrane. The coated portion of the membrane then extends from the body of the cell and surrounds the particle, eventually enclosing it. Once the vesicle containing the particle is enclosed within the cell, the clathrin disengages from the membrane and the vesicle merges with a lysosome for the breakdown of the material in the newly-formed compartment (endosome). When accessible nutrients from the degradation of the vesicular contents have been extracted, the newly-formed endosome merges with the plasma membrane and releases...

...ton will create Proton Motive Force. PMF is then used by ATP synthase to create ATP, as the immediate movement of protons back down along the gradient concentration of H+. ATP synthase is like a turbine that will move/rotate when protons run down along it. The movement of protons via ATP synthase will power this turbine to energize and synthesize ATP from ADP + Pi

- 1. Discuss the Guidelines from the National Cholesterol Education Program Expert Panel on Detection, Evaluation and Treatment of High blood Cholesterol ----Adult treatment Panel (ATP III) for fat (total & saturated fat) intake and compare fat intake (based on the 3-day averages) to these recommendations. 1) Thousands of people in the United States died from coronary artery disease (CAD). And many people today live with complications from the disease. It is the goal of the National Cholesterol Education Program (NCEP) to reduce the morality and the severity of the disease....

- ... Accordingly, SFA provide a dense source of energy for the body. We cannot completely illuminate SFA from the diet, because fat energy needs wouldn’t be met. Another advantage to SFA is that they increase HDL cholesterol (1st review). Good levels of HDL are (Webmd.) 60 mg/dL and low are 40 mg/dL. HDL is important because it removes free cholesterol from extra hepatic tissues. It also transfers cholesterol esters to VLDL or delivers them to the liver: There, HDL is degraded and cholesterol is released.... [tags: Cholesterol, Atherosclerosis]

- ... (3)feasibility of recommendation According to the recommendation,there is no strict rules for fat consumption.Full fat diet also contain unsaturated fat which have been associated with lower LDL level.From the data of NDNS,public should also consider UFA as one of the major source of fat intake.Nuts,milk products,plant oil especially olive oil, soybeans, vegetables and meat are major source of UFA.Check the consumption of fat intake from figure 5 and 6,we can conclude these are also major source of total fat and saturated fat.So,it is easy to have a full fat diet.While,the recommendation for sugar is impractical to achieve the recommendation standard.From figure 8,it can be seen that...

- Paying by the Pound: Why a Fat Tax Would Not Work in America Obesity is something that we have all seen before. In this day and age, it has become far more prevalent than any year in the past and is only gaining speed with time. Obesity has become a plague making its mark on our country and on our world. In 1962, obesity in the United States was approximately 13.4 percent of the population (Fryar, Carroll, and Ogden 5). That number in 2010 was 36.1 percent, a huge increase that is detrimental to the health of Americans (Fryar, Carroll, and Ogden 5).... [tags: Nutrition, United States, Obesity, Saturated fat]

These tests are able to identify RNA, genes, and protein sequences which play a role in diseases. These sequences may be linked to diseases which include nucleotide polymorphism, deletions, rearrangements, and many more. Molecular Diagnostics is also able to identify and multiply the presence of certain microorganisms and cells. Molecular Diagnostics provides a great amount of clinical information....

- Weight and Activity Level I consumed 689 calories during the three-day study diet. My DRI (Daily Recommended Intake) is 2,207 calories. I believe that I consumed more than 689 calories during all of the three days combined. My first day, June 15, I added up the calories of the foods I had for lunch and they totaled at 972 calories; it was only for one meal and it is 283 calories over the number of calories iProfile indicated that I consumed for the whole three days . My energy balance on iProfile correctly calculated the total calories I consumed throughout the three days but my average intake is still 689.... [tags: Nutrition, Vitamin, Food, Fat]

- Based on the information I put into the food tracker, I am not doing so great with my diet. It could be worse but it most definitely could be much better. I did not meet any of the required goals for any of the food categories recommended by the USDA. I did not eat near enough fruits and vegetables while my protein levels were somewhat ridiculous. My fruits, vegetables, grains, and dairy were all under the specified amount while my protein was very high. The fat and dairy level was OK as well as my oils intake....

Compared to my RDA estimated energy needs of 2293, I can see that my calorie intake is surprisingly low. At the moment I am only fulfilling less than half of my caloric/energy needs by 42%, placing me under. In reality, I feel like I would constantly eat more throughout the day than I should. Maybe this is because in the past, I would eat empty calorie or high calorie foods.... [tags: Nutrition, Vitamin, Fat, Saturated fat]
