Iron is an essential element for the human body and must be obtained from our diet. The concentration of iron in our body is low compared to the abundance in the environment. The average human body can store up 3-4 mg of iron depending on gender. Women need more iron in their nutrition than male because of the loss of blood through menstruation and childbirth. Iron quantity in our body is relatively small because an excess of it can damage our tissues; therefore, iron homeostasis is crucial in our body. Iron is regulated in the human cell in order to avoid damaging the human cell and tissues, and to make up for it being lost through the shredding of the epithelium cell. Iron is needed for several functions in the body. It acts as a cofactor …show more content…

Iron is used for several different activities in our body. It can be stored in the liver, bone marrow, and used by hemoglobin. It is also absorbed by part of the small intestinal called the duodenum. Iron exhibits two forms in our body, ferrous Fe2+ or ferric Fe3+, depending on what part of your body it is used in. When iron is absorbed by the duodenum it is taken to the lumen apical. In the lumen, iron is ferric (Fe3+) and needs to be reduced to ferrous (Fe2+) to cross the plasma membrane. On the surface of the membrane, ferric iron (Fe3+) is converted to ferrous by ferric reductase. The symporter called Divalent-metal transports Fe2+ with protons into the cell. Iron is transported into the cell by active transport. When ferrous enters the epithelium some irons are converted to Fe3+ which are stored in the cell at the mucosal ferritin and lost by shredding of epithelium cell. Some iron is used in the mitochondria in the electron transport chain. The rest of the iron is transported out of the epithelium cell into the blood by the ferroportin and immediately converted from Fe2+ to Fe3+ by the Hephaestin. As iron gets into the blood it is bound to the transferrin and transported to various parts of the …show more content…

Iron is part of the heme in the hemoglobin found in the red blood cell. Heme can be recycled after the red cell has died. Iron is regulated by the live, therefore, excess of iron storage in the liver can also trigger a negative feedback in the epithelium cell. when the liver stores enough iron it releases a Hepcidin. Hepcidin inhibits the ferroportin from release any more iron into the blood circulation. Hepcidin is the major regulator of iron in the human body. Iron can also be used in the mitochondria in the synthesis of iron-sulfur cluster and heme. Heme in the mitochondria is found in the cytochrome used in the electron transport chain. Iron also place a role in the cofactor of an enzymatic reaction in the central nervous

The blood seeps in the sinusoids on its way to the hepatic veins, and then to the vena cava. This filtration is ideal for hepatocytes to filter the blood, process and store nutrients, cleanse, and remove debris. 6. Cirrhosis leads to scarring and increased hydrostatic pressure in the hepatic portal vein. Explain why this increased venous pressure causes net filtration to increase in the hepatic capillaries, leading to ascites (swollen and fluid-filled interstitial space of the abdomen).

After a while, a brownish color substance started to form on the three iron nails. We predicted that the brown substance on the nails is copper because the reaction of copper(II) chloride with iron is a single displacement reaction, so copper would be produced. 0.48 grams of iron was used in the reaction because 2.73 grams subtracted by 2.25 grams is 0.48 grams. The 0.48 grams of iron had to be used in the reaction with copper(II) chloride in order to produce copper, according to the reaction equation: CuCl2+FeFeCl2+Cu. 0.52 grams of copper was produced after pouring out the copper(II) chloride solution and the three iron

My diet contained enough iron to meet the recommended value. I had consumed 21mg of iron while the recommendation was to consume a daily amount of 18mg. The foods that contributed the most iron to my diet were chicken, beans, and almonds, and raisins. Foods such as red meat, chicken, and seafood such as clams contains the most iron in the majority of foods one can consume.

Iron carries oxygen from our lungs through the bloodstream and releases it in the body where it’s needed. Iron is built into the enzymes that do most of the chemical heavy lifting in our bodies, where it helps us to detoxify poisons and to convert sugars into energy.” Despite being a vital mineral, too much of anything can be detrimental for the human body; therefore, introducing

1.5) judge by using some examples; write the importance of maintaining a constant internal environment in different condition at high temperature, low temperature, severe vomiting and too much fluid intake. Homeostasis is the procedure through which a life form keeps up certain interior conditions, for example, a human body 's inward systems keeping up body temperature at a particular level to anticipate over or under warming; this procedure is vital in light of the fact that it makes it workable for cells and organs to work legitimately. For instance, certain parts of the human body stop to work on the off chance that they turn out to be excessively hot or excessively frosty; this is the reason it is feasible for individuals to stop to death

1. Introduction: a. Hemoglobin structure: Hemoglobin is metalloprotein found in red blood cells having four polypeptide chains. Adult hemoglobin contains 2 alpha (141amino acid) and 2 beta chains (146 amino acid) which forms a tetramer called as globin and each chain is attached to iron containing prosthetic group heme (protoporphyrine IX). Ferrous ion of this heme is linked to globular protein by binding ‘N’ in the center of the protoporphyrin ring. There is a non-covalent interaction between four chains.

Task analysis: From what I understand from the question, I will describe why iron is required in a balanced diet. Iron is a mineral and minerals play a vital role along with vitamins and other nutrients to keep our body healthy. Iron is a trace mineral, which means that our body only requires it in miniscule amounts. Without iron in the body, red blood cells will lack the ability to transport oxygen to all parts of our body which will lead to anemia, a condition whereby

He had a big arc reactor to power the energy needs for the stark tower. While he was inside that cave, he made a small arc reactor that also acted as an electromagnet which functioned: to keep that shrapnel away from his heart and to power the first iron man suit. When he escaped from the cave, he created a new and better version of the arc reactor which is way more powerful than the previous one. However, this arc reactor had a palladium core which slowly poisoned his blood. So he discovered a new element to power his arc reactor.

Any diet that brings permanent damage to vital parts of the body should not be considered as a healthy diet. Also, meat contains vitamin B12, therefore meat incorporated diets possess a lower possibility of serious health issues from lacking vitamin B12. In addition to vitamin B12 deficiencies, vegetarianism does not supply as much iron as a generic diet would. According to the Office of Dietary Supplements at the National Institutes of Health, “The body absorbs 15% to 35% of the heme iron in meat, but only

As time passes by, people are starting to pay more attention to their health which has led some to being meticulous on the food that they eat. They began to alter their usual dietary choices and resort to vegetarianism. The number of vegetarians has been significantly increasing over the years but during those years, such people continue to customize their diets which resulted to the different types of vegetarians. One type has created a diversion in opinions and becomes subjected to never – ending debates – the vegans. Vegans are strict vegetarians, meaning they totally omit any type of meat from their diet.
