What is Homeostasis? For the human body to function optimally, each bodily system must operate within certain conditions for the performance of each cell. Many cells do not perform properly if the body’s internal environment changes drastically from a predetermined ‘set point’ where they operate efficiently. To preserve this set point, each system must maintain constant requirements and regulate any changes to stay within this range.

In many cases the association process is a part of biological function as in blood clotting or the formation of muscle fibers. Aggregation of proteins also leads to perturbation of the biological function with sometimes serious physiological consequences as in the formation of cataracts in the lens of the eye or amyloid fibrils associated with Alzheimer’ and other neurological diseases. From a colloid chemistry perspective, protein self-association is a special case of the general problem of colloid stability. There are two important aspects of the protein systems in this respect: first in contrast to colloids in general the system can be obtained in pure form and then represent a true single component. Second the protein has a complex molecular structure and one should expect protein- protein interactions to be highly directional.

The oxidation of these molecules is primarily used to transform the energy contained in these molecules into ATP. ATP os a large source of energy for muscle contractions and can therefore be referred to as "energy currency" of the cells. The fuel molecules is first converted into acetyl-CoA and then can be inserted in the Krebs Cycle. Looking at the path of a nutrient, such as glucose, the oxidation of the molecule takes place in the glycolysis.

  The size of the pore matters as well.   Diffusion is when the movement of molecules from an area of high concentration to an low area concentration.     Osmosis is the movement of water

As a result, the gastric becomes unable to secrete the basic materials such as hydrochloric acid, pepsin acid, and IF. Hydrochloric acid and IF are important to absorb vitamin B12. However, the patient who has atrophic gastritis cannot absorb vitamin B12, which is leading to vitamin B12 deficiency. The third cause is vitamin B9 deficiency (folic acid deficiency). Folic acid is important to the formation erythrocytes and reparation the damaging cells, so folic acid deficiency caused decreasing the number of healthy erythrocytes, which causes pernicious anemia.

If the concentration of glucose in the blood is low / below the normal range, it leads to the secretion of glycogen from the alpha cells. Glycogen will change the energy stores such as glycogen in the liver to the glucose (stimulates the breakdown of glycogen) by increasing the level of sugar in the blood(ibid).

The harm is caused from insufficient amount of vitamin D in the body mainly due to the inability of converting the vitamin into its active form. The most common source of vitamin D is the skin. Objectives

H2S is also involved in reducing angiotensin II production and inhibiting bradykinin degradation, thus maintaining blood pressure (Laggner et al., 2007). H2S also plays a role in the regulation of renal function. It increases renal blood flow, glomerular filtration rate and urinary sodium and potassium secretion, hence regulating blood pressure (Hart,

Prokaryotic organisms normally have a cytoplasmic membrane, cell wall, and sometimes a capsule. Bacterial cells are most commonly either coccus or bacillus in shape. The cell wall is either Gram positive or Gram negative. When the cell is Gram negative, the cell has an extra layer of lipopolysaccharides. The Gram positive has a thick layer of peptidoglycan.

Since it is not as efficient that human body is forced to make its food out of glucose. As stated before this type of respiration occurs when the body is undergoing intense exercise where minimal oxygen is needed and mostly glucose is used. Because of this a fluid known as lactic acid is produced and spread throughout the body causing muscle pulls due to the lack of oxygen. The respiration rate in humans is affected by a number of different factors such as age, weight and the intensity of exercise.

Even though transport proteins are involved in facilitated diffusion, it is still considered passive transport because the solute is moving down its concentration gradient. Facilitated diffusion speeds up the transport of a solute by providing an efficient passage through the membrane, but it does not alter the direction of transport. Active transport requires energy to move a solute against its concentration gradient. As in most other cellular work, ATP will most often provide this energy, usually by transferring its terminal phosphate group directly to the transport protein. With ATP, the donated phosphate group induces the transport protein to change its shape in a manner that translocates the solute bound to the protein across the membrane.

Overview Unlike overdoses of many substances, sugar "overdoses" don't lead to toxicity reactions--though in extreme cases, they can cause dehydration, which has its own set of side effects. Instead, a sugar overdose leads to two separate problems: high blood sugar, and over-consumption of calories. Each of these are associated with side effects. Sugar High

Question / Problem: What is the evidence to recommend Trulicity (dulaglutide) to a patient who has uncontrolled glucose control, and is on metformin and insulin (levemir) and non- adherence to the insulin. Response: The trulicity is a non-insulin injectable with dosing regimen of once weekly dosing. These agents work by activating GLP-1 receptors in the pancreas, which leads to enhanced insulin release and reduced glucagon release-responses that are both glucose-dependent-with a consequent low risk for hypoglycemia.

permitted through facilitated diffusion involving glucose transporters. Glucose transporters are specialised for different cell types, for muscle and fat cells, type 4 glucose transporters (GLUT4) are used, as muscle cells are vital to athlete performance in the rainbow rage, GLUT4 shall be examined in this example. Firstly, insulin binds to insulin receptors on the surface of the cell. This sends a signal to GLUT4 vesicles from inside the cell initiating their movement to the cell wall. GLUT4 vesicles fuse to the outer cell membrane, catalysing the movement of glucose into the cell, this is the major endocytic process within cells.

Fed Up is a documentary made in 2014 that is based on the issues caused by the American food industry. Fed Up, uncovers America’s true secrets about the food people consume every day. More specifically, it reveals the affect sugar has on people’s bodies. As a result, the amount of sugar in food, the bodies consent of glucose, and the satisfying taste it brings, too much sugar could cause certain sicknesses causing the body to not work the way it supposed to. To start off, the amount of sugar put in America’s food is predominately high.
