  • The Role Of Macromolecules In Eukaryotic Cells

    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 (, 2016). These are contained inside of a plasma membrane which are made up of phospholipids and can fuse…

  • Impact On TRMPLIV

    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…

  • Organelles Of Animal Cells Essay

    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 Experiment

    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…

  • Lysosomes Research Paper

    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…

  • Lysosoma Research Paper

    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…

  • Ribosomes Essay

    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.…

  • Prokaryotic And Eukaryotic Cells Essay

    The role is to form proteins by assembling amino acids. The proteins are needed to carry out the cells activities. Endoplasmic reticulum- These are only found in eukaryotic cells. It is made up of sac like structures and held together by a cytoskeleton. Rough endoplasmic has a surface dotted with proteins and the smooth endoplasmic is made up of tubules which increases surface area. They insure there is more surface area for cell reactions. Also involved in making nuclear membranes during the…

  • Amino Acid Sensor Lab Report

    Aim 2: How does folliculin detect amino acids to regulate mTORC1 activity? Here, the goals are to elucidate the mechanism of action that enables folliculin to function as an amino acid sensor. 2.1. Determine the amino acid reservoir folliculin senses. Evidence points FLCN as a novel amino acid sensor. To resolve the biochemical mechanism FLCN employs, we need identify the specific amino acid reservoir FLCN senses. Lysosomes’ are the main amino acid reservoir and the ‘inside-out’ mechanism is a…

  • Organelles Essay

    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.…
