astrocytes. It will prevent the astrocytes from taking up and recycling the glutamate at the synapse. When glutamate binds to receptors on the MN, it causes a cascade of reactions which results in the uptake of Ca+2 ions. The excess Ca+2 ions causes organelles inside MN to malfunction resulting in apoptosis (Foran and Trotti, 2009). Astrocytes from FALS patients cultured with healthy MN resulted in the death of at least 50% of the MN compared to a control that contained healthy astrocytes and…

proerythroblasts to form erythroblasts. The formed erythroblast synthesizes hemoglobin and begins to shrink to a normoblast. The nucleus is then ejected from the normoblast forming a reticulocyte. When the reticulocyte enters the blood stream, the organelles contained begin to degenerate and is then considered a mature erythrocyte. Thrombopoiesis produces the platelets and begins with a myeloid stem cell, which produces the progenitor cell when stimulated and becomes a megakaryoblast. The…

Primary central MEC has been reported in the first to seventh decade; however, cases occurring in the: fourth and fifth decades are most widespread. [6] In children, gender ratio and the mandible to maxilla ratio is 1:1, whereas in adults: MEC is slightly more common in women and the posterior mandible. [6] In this case the lesion was seen in 16 yr female patient. The pathogenesis of intraosseous MEC is much debated. It may originate from, [7] • Entrapment of retromolar mucus glands within the…

Question and Hypothesis Experiment I Eukaryotic cells contain several membrane-bound organelles. Plant cells are a specific type of eukaryote that are both aerobic and photosynthetic. Because of this, they contain mitochondria that serve a vital role in aerobic respiration that follows photosynthesis. The enzyme succinate dehydrogenase (SDH) is an enzyme associated with the Citric Acid Cycle that takes place in the mitochondrial matrix. SDH serves as a catalyst for a reaction in which succinate…

into mitochondrial genome. https://www.medicinenet.com/script/main/art.asp?articlekey=4402 The mitochondrial inheritance is caused by mutations in the mitochondrial DNA that is maternally inherited from the mother. The Mitochondria is structure of organelles, that is found in the cells located in the cytoplasm outside the nucleus. The mitochondria job is to manufacture energy in each of the cells and throughout the body https://www.medicinenet.com/script/main/art.asp?articlekey=4402 .The…

The immune system is a highly integrated, diverse task force the body recruited with the sole mission of protection against invading forces of infection, pathogens and mutant cells. The immune system is always surveilling for the enemy through its ranks of innate immune cells which lack memory and specificity including, neutrophils, basophils, eosinophils and monocytes. These cells patrol and destroy anything suspicious whether they have seen it before or not and have the ability to alert higher…

Introduction: - Mitochondria is a double membrane organelle that is found in all eukaryotic organism. There are some evidences that proves that some of the eukaryotic organism lack this organelle but there is no true evidence which says that this specific organism completely lacks mitochondria. Mitochondria is also known as a power house of the living body cell. It stores energies in the cell and releases when its needed. Every organelle in Mitochondria have their own specific roles which helps…

mountain and valley areas, the desert, as well as city areas populated mainly by humans. The owl that I want to concentrate on is the great horned owl. The owl is classified as a Eukarya because it has a true nucleus and possesses membrane-bound organelles. This is a very powerful bird and gets its name from the tufts of feathers on its head that look like horns. These tufts like they may be the ears of the owl,…

will be talking about how curry and cinnamon affect bacteria. The first thing is what is bacteria. So, bacteria are good in many was as it is also bad, bacteria is a member of a large unicellular microorganisms that have cell walls but they lack organelles and an organized nucleus, including some that can cause disease. Bacteria is found everywhere, in the air, soil, water, and inside your body…

1. (a) Diffusion refers to the movement of molecules from an area of high concentration to an area of low concentration of those molecules. The factors that influence the rate of diffusion across a membrane are: ~ the extent of the concentration gradient – the greater the difference in concentration on either side of the membrane, the faster the rate of diffusion ~ the mass of molecules diffusing – the heavier they are, the slower they will diffuse across the membrane ~ the distance travelled –…
