The Stomach Of The Cell

The vacuole has many different jobs but all the same in importance. For example, the vacuole keeps the cell clean; it holds the trash that the other organelles leave behind. This organelle also is the reason why plants stand straight. In addition, the vacuole holds water and other nutrients for plants.

Lysosomes – Lysosomes act as the digestive system of the cell. They are found in all parts of the cell. There are very powerful enzymes within lysosomes.

The stomach is an organ that is part of the digestive system. The stomach is located in the upper left part of the abdominal cavity, below the diaphragm and next to the liver (Stomach, 2013). The inner walls of the stomach contain small pores called gastric pits. The gastric pits contain cells that secrete chemicals that aid in the digestion of food (Nguyen, 2015). In this essay, I will discuss the different cell types of the stomach, how they work together to provide the overall function of the stomach, why each organ requires different cell types, why the stomach can’t be comprised of just one cell type, and the advantage of having different types of cells.

They are very important in the synthesis and packaging of proteins. Some of those proteins might be used in the cell and some are sent out. The ribosomes are attached to the membrane of the ER. As the ribosomes builds the amino acid chain, the chain is pushed into the ER. When the protein is complete, the rough ER pinches off a vesicle. That vesicle, a small membrane bubble, can move to the cell membrane or the Golgi apparatus

There have been many attempts at preventing malaria, none of which have been very successful. These have usually involved protecting human beings from mosquitoes, the dreaded carriers

P1 – Describe the microstructure of a typical animal cell and the functions of the main cell components. A typical animal cell is seen as a tiny, three dimensional sac which is in fact made up of many components, each as important as the other. The microstructure of an animal cell was in fact uncovered mainly through the use of both cell fractionation and electron microscopy. Each main component has its own, individual function which helps a cell to function and maintains the cell membrane. The components that I will be describing include the cell membrane, nucleus, cytoplasm, mitochondria, lysosomes, Golgi bodies, centrioles, endoplasmic reticulum (both smooth and rough) and ribosomes.

For my argumentative essay I am choosing lysosomes. Lysosomes clean up the cell leaving a clean place for the other organelles. If lysosomes were removed the cell would be filled with unneeded debris. The cell would eventually be too full and wouldn't be able to perform the job of the cell.

The endothelial barrier becomes leaky allowing parasitic infection to commence. Other symptoms of Plasmodium falciparum parasitic infection are anemia. Because of the infection of red blood cells, anemia is highly likely once infected with the parasite. This is because of the lack of healthy red blood cells are circulating the human body. Examinations for a link between anemia and malaria have been conducted through the RSP2 surface protein. Through surface protein tagging, evidence has supported that the link occurs through sequestration, as larger amounts of red blood cells clump together (Layez et al., 2005). This unique molecular mechanism for destroying red blood cells was examined through the antibody response once anemia was witnessed. A chronic form of anemia can be observed. Anemia is common through the Plasmodium genus because all three species of Plasmodium infect red blood cells. Plasmodium falciparum not only can cause chronic anemia in most humans infected, but it can also be selective based on genes present in humans that can deter red blood cell infection. Another virulence factor to consider for this species is that of cytoadherence. During infection, this parasite releases adherence proteins, which incorporate themselves into the outer membrane of red blood cells. These proteins then attach to endothelial cell receptors in blood vessels preventing these infected cells from being cleared out by the spleen (Cholera et al., 2008). It is

Study of exosomes has become popular in recent years, exosomes which are mainly found in body fluids such as blood and urine may play a role in cell biology and in the immune system. In eukaryotes, some cells are responsible for receiving signals via chemokines or cytokines, taking up nutrients and secreting proteins into extracellular space, endocytosis and exocytosis are then involved.

Eukaryotic cells can massively transfer their own cytoplasmic contents into a lytic compartment, the vacuole/lysosome, for reprocessing through a conserved system called autophagy. The key process in autophagy is the separation of cytoplasmic

In 2012, the recent statistics provided by World Health Organisation showed approximately 207 million cases of malaria worldwide and an estimation of 627000 deaths (WHO, 2014). It also displayed that mortality rate of the disease has globally declined by 42% but in African region, the mortality rate of malaria is about 49%, which is a slight difference when compared to the worldwide mortality rate (WHO, 2014). Statistics showed that most mortality occur amongst children residing in Africa, in which a child “dies every minute from malaria” (WHO, 2014). Although there have been an advancement in knowledge relating to the disease, it is continuously a major cause of morbidity and mortality in the world.

As the mouth is the first site of chemical digestion and uses enzymes to break down the food we eat, lysosomes are likely the most numerous organelle inside your mouth. Lysosomes are organelles which contain enzymes that are capable of breaking down many different substances. Some of the substances that lysosomes can break down are proteins, nucleic acids, carbohydrates, and lipids. As lysosomes function as the digestive system of the cell, serving both to degrade material taken in by the cell as well as to digest components of the cell itself, it makes sense that lysosomes would be the most plentiful organelle in the mouth.

Among the three promising PI(3)P-interacting partners, the mammalian orthologues of PfHsp70-1 have been reported to bind several anionic phospholipids including phosphoinositides, implicating conserved lipid-binding pockets in PfHsp70-1. Furthermore, the human Hsp70 has been shown to be associated with lysosomes via binding to a lysosomal membrane lipid and may stabilize the lysosomal membrane under cellular stresses. The functional counterpart of lysosome in Plasmodium is the acidic food vacuole where hemoglobin is digested. The fact that PI(3)P is heavily

Malaria is a serious infectious disease and sometimes fatal. A parasite known as a protozoan, which is a single celled microorganism that lives within the host is the cause for this potentially deadly disease. In this case, the host is a mosquito. “There are 430 various genus Anopheles (mosquito) species, but only 30-40 species carry the malaria parasite. There are many other species of mosquito’s that do not carry the malaria parasite, approximately 3,500 types in all.” They are broken up into 41 different classes such as the Culex Tarsalis that causes West Nile Virus and many more. Malaria is not contagious in the normal sense of the word. You cannot catch it by sneezing or coughing on someone. Anyone who has the disease will find Malaria in the RBC. The most common mosquito bites that carry the malaria virus are the Plasmodium Falciparum and Plasmodium Vivax, which usually bite from dusk to dawn. The most severe and deadliest malaria is from the Plasmodium Falciparum of the genus anopheles species, found in Africa and New Guinea.

Malaria is a disease that has been known for more than 4000 years as swamp fever disease which greatly infects the human populations and human history (4). The origin of the word malaria is Italian, a reduction of mala aria, bad air, and that goes back to the belief that the disease was caused by toxic and poisonous air in the swampy regions. According to some medical terms, the first use of the word “malaria” was by Francisco Torti, an Italian physician (1658-1741) (5). Moreover, the discovery of the malaria parasite goes back to Charles Louis Alphonse Laveran, who was a French surgeon in 1880 (4).
