  • The Endoplasmic Reticulum

    1644 Words  | 7 Pages

    1. Introduction The endoplasmic reticulum (ER) is the central intracellular organelle providing stringent quality control systems to protein synthesis. Upon accumulation of misfolded/ unfolded proteins in the ER, eukaryotic cells have developed an evolutionarily conserved adaptive mechanism, unfolded protein response (UPR), to clear these proteins and restore ER homeostasis. The ability to respond to perturbations in ER function is critical for cell survival but chronic or amplified ER stress can

  • The Microstructure of a Typical Animal Cell Essay

    1804 Words  | 8 Pages

    that I will be describing include the cell membrane, nucleus, cytoplasm, mitochondria, lysosomes, Golgi bodies, centrioles, endoplasmic reticulum (both smooth and rough) and ribosomes. The cell membrane - The cell

  • Endoplasmic Reticulum ( Er ) Stress Response

    3056 Words  | 13 Pages

    Abstract Endoplasmic reticulum (ER) stress response may be mediated by HRV16 nonstructural proteins 2B, which share similar characteristics to CVB3 2B. To understand whether HRV16 2B induces an ER stress response, a HRV16 2B fusion protein with GFP were generated and its effects on ATF6a (activating transcription factor 6a), IRE1 (Inositol-requiring enzyme 1), and PERK (PKR-like ER protein kinas) expression in BHK cells were determined. The results showed that HRV16 2B induced significantly high

  • Taking a Look at Niemann-Pick Disease

    1294 Words  | 5 Pages

    Niemann-Pick disease an inherited condition involving lipid metabolism, which is the breakdown, transport, and use of fats and cholesterol in the body is the condition in which abnormal lipid metabolism causes harmful amounts of lipid to accumulate in parts of the body. There are 3 forms of this disease: Type A, B, and C. The general focus of this paper will be Type C. Niemann-Pick’s disease Type C (NPC) is disease in which unesterified cholesterol and other lipids accumulate in late endosomes/lysosomes

  • Essay on Make-up of Life-giving Cells

    991 Words  | 4 Pages

    What is a cell? A cell is “the structural, functional and biological unit of all organisms” (biology-online.org). The millions of cells that compose the body give life. These cells work together in synergy to perform the bodily functions God has given man to maintain homeostasis. The cells that work in harmony consist of an array of cells such as, epidermal, nerve, or muscle. As these various cells work together they form a biological machine to give life. Before the discovery the cell, many had

  • Role Of Grp170a In C. Elegans

    760 Words  | 4 Pages

    GRP170 is large protein that belong to the HSP70 superfamily of molecular chaperones that are located in the lumen of the endoplasmic reticulum, these class of proteins assist with properly folding polypeptides into proteins, these chaperones are also utilized in the Unfolded Protein response in the endoplasmic reticulum. Caenorhabditis elegans contain two paralogues of the GRP170 gene, GRP170a and GRP170a. The expressions of these two loci of the gene occur at different instances and are induced

  • Different Types Of Cell Found Within The Human Body

    968 Words  | 4 Pages

    organelles exist within the cells of the human body, (Biology, 2015). Rough and Smooth Endoplasmic Reticulum, Mitochondria, Vacuoles, The Nucleus, and many more can be found within the cell. Rough Endoplasmic Reticulum, or simply ‘Rough ER” is studded with protein builders known as ‘Ribosomes’ and is used within the human body to manufacture lysosomal enzymes and secreted proteins. Smooth Endoplasmic Reticulum or ‘Smooth ER’ is characterised by its lack of Ribosomes. Its uses within the body include

  • What Are The Importance Of Organelles In Animal Cells And Animal Cell?

    972 Words  | 4 Pages

    important for the cell to survive. Each organelle has a specific function for the cell. The types of organelles in the cell can be different from each other depending on the type of cell. Plant cells and animal cells both have a cytoskeleton, endoplasmic reticulum (smooth and rough), golgi apparatus, mitochondrion, nucleus, plasma membrane, and ribosomes. Animal and plant cells also have vacuoles, but they are rarely found in animal cells. Vacuoles in animal cells are very small compared to the vacuoles

  • Human Physiology : Cells And Tissues

    2541 Words  | 11 Pages

    UNIT 4: HUMAN PHYSIOLOGY CELLS AND TISSUES This is a diagram of an animal cell with all its key components labelled The structures within an animal cell are described as follows: Plasma Membrane or Cell Membrane: This is a thin membranous layer which surrounds the cell and acts as a barrier, it works to separate the contents within the cell from its external environment as well as from other cells. It 's structure is important as it provides structural

  • What Are The Three Postulates Of Cell Theory

    1009 Words  | 5 Pages

    Functions Based on Bolsover et al. (2004), a cell has parts, structures or organelles (Table 2) that have a respective function as a whole for life to occur (Figure 2). Generally, cells have parts such as nucleus, mitochondria, Golgi apparatus, endoplasmic reticulum, lysosomes and cell membrane. Different structure has different function but working as a whole. One structure cannot make life possible but many complex structures and functions contribute to the existence of
