Lysosome

Eukaryotic cells are cells whose nucleus is bound by a membrane; these cells contain organelles, which are structures each enclosed within its own membrane found only in eukaryotic cells, each organelle has a specific function inside a cell. One type of organelle is a lysosome, which are the organelles that dispose of waste and toxins. Lysosomes are fluid filled sacks which range in size from 0.1 to 1.2 micrometres and contain around fifty degradative enzymes that enable it to effectively dispose of unwanted substances inside of a cell; this includes excess and faulty organelles, food particles, viruses and bacteria (Micro.magnet.fsu.edu, 2016). These are contained inside of a plasma membrane which are made up of phospholipids and can fuse…

Lysosomes are one of the abounding organelles that make up a typical eukaryotic cell. A typical human cell contains hundreds of lysosomes but can be found in much higher quantities in cells more directly involved in exocytosis and cells of the immune system. Under a microscope, lysosomes can be observed as spherical-shaped, tiny membranous sacs composed of a single phospholipid bilayer that separates the acidic interior (pH 4.8-5) from the rest of the cell. The acidity is maintained by the…

TRPML1’s Impact on MLIV In the article, “Fusion of lysosomes with secretory organelles leads to uncontrolled exocytosis in the lysosomal storage disease mucolipidosis type IV” discussed the impacts of TRMPL1 on MLIV. Lysosomes are important in maintaining healthy cells, however, with the absence of lysosomal TRP channel TRPML1 then the lysosomal pH becomes more acidic because of the calcium leakage; hence, this makes lysosomes more sensitive to fusing, and due to being near exocytosis regulating…

single nucleotide with two extra energy storing phosphate groups. When food molecules are broken down inside cells, some of the energy in the molecules is stored temporarily in ATP. Cells need a steady supply of ATP to function. The Golgi apparatus helps the cell maintain homeostasis by modifying, sorting, and packaging proteins to transport. It is a set of flattened; membrane bound sacs that serve as the packaging and distribution center of the cell. Enzymes inside the Golgi apparatus…

Lens Fiber Differentiation and its effects on certain organelles. This writing exercise analyzes two separate but related scientific articles, “The fate of the Golgi Apparatus and the Endoplasmic reticulum During Lens Fiber Cell Differentiation” and “Coincident Loss of Mitochondria and Nuclei During Lens Fiber Cell Differentiation” both which analyze and study Lens Fiber Differentiation. The writing assignment will be based on four sections:(1) Background of the research (2) Methods used…

Describe the structure and function of a lysosome. Lysosomes are a cell organelle, translating as an independent structure within a cell, possessing a specific structure and function. For a lysosome its functions include; digestion of intracellular or extracellular material, nutrition from digested macromolecules and defence/protection from harmful substances. Lysosomes are variable from cell to cell in terms of shape and size but are conventionally spherical or oval shaped, 0.5µm in diameter…

Brian Diaz & Emilio Hernandez Biology Honors Dr. Odom 12-4-17 Curing Cancer: Lysosome & Active Transport For this research project we used lysosomes as the cell structure and active transport as the cell capability. We used these factors in order to find a cure for breast cancer. The reason we chose breast cancer is because if anything were to go wrong we would have the capability of having a mastectomy before the cancer can spread. However, with lung cancer we don't have the ability to…

its function. Some of the secretory vesicles which hold hydrolytic enzymes stay within the cytoplasm and function as lysosomes. Lysosomes. Lysosomes are specialized vesicles that are created by the Golgi body. Their role is to digest any worn out, excess or unwanted bodies within the cell. This could include bacteria or viruses as well as mitochondria which are no longer effective. To do this they contain an acidic (pH 4.5–5) hydrolytic enzyme mixture that is housed in a single membrane.…

traveling from the receiving to the shipping side of the Golgi apparatus. Once on the shipping side of the Golgi apparatus they are carried through transport vesicles to other organelles or the plasma membrane. Lysosomes develop from vesicles that bud off the Golgi apparatus. Lysosomes are membrane-enclosed sacs of digestive enzymes found in animal cells. Lysosomes are not usually found in plant cells. Proteins, fats, nucleic acid and proteins are broken down by enzymes in the lysosomes.…

Cancer, Lysosomes, and Treatment Cancer is one of the most leading causes of death across the world. Several therapies exist to fight cancer. They include surgery, radiation therapy, stem cell transplant, targeted therapy, hormone therapy, and immunotherapy. One common therapy many chose is chemotherapy. Chemotherapy is cancer treatment using one or more anti-cancer medications that are given as a standardized regimen. There are several types of chemotherapy medications. Alkylating agents attack…
