  • Nucleus Essay

    Nucleus The Nucleus is an example of a command centre found inside a eukaryotic cell; it’s usually the most prominent organelle, yet it occupies only 10% of the total volume of the cell. If this cell did not have a Nucleus, it would be defined as a prokaryote cell, however if the Nucleus was damaged and not repaired, the cell would simply die. The cell nucleus is enclosed within a double membrane (contains an Inner and Outer Nuclear Membrane) called the Nuclear Envelope, which separates the…

  • Essay On Cell Theory

    and in combination with the cell membrane, provide the cell the structure. The mitochondria provide the cell with power while the vacuoles stores nutrients for the cell. There are more organelles such as the ribosomes, lysosomes, centrioles, Golgi apparatus, peroxisomes and the cilia and flagella that all do certain jobs for the cell and require the cell to function. These parts or organelles may not be living, but they are still important for every living…

  • Chloroplast Theory

    throughout the cell. They are created by the rough endoplasmic reticulum, sent to the Golgi apparatus and then finally become lysosomes. Their main function is to float around the cell and when the cell eats or consumes energy, the lysosomes burst into action to consume the energy. Even though lysosomes jobs are to break down other energy and organelles in the cell, it doesn't break down the cell's membrane. The Golgi apparatus looks similar to the rough ER yet they are two completely different…

  • Microtubules Research Paper

    Microtubules, which are made of protein subunits called tubulin, are the thickest of all three cytoskeletal filaments. Microtubules are mainly serving as the paths along which vesicles are guided in their travels to various destinations, and are responsible for associating with motor proteins attached to the vesicles. Microtubules can also expand or shrink in length in order to establish dynamic structures that can efficiently change the internal organization of the cell, and capture organelles…

  • Ribosomes Essay

    They are made within the nucleolus from 60% RNA and 40% protein, and consist of two subunits, one large and one small. When produced, the subunits stay separate to exit through the nuclear pores: it is only because of their miniscule size that they can fit through. Many ribosomes then bind themselves to the RER, although some stay free in the cytoplasm. Free and bound ribosomes both create polypeptide chains, which are used to make proteins. To create a polypeptide chain the large and small…

  • Oxysterol Essay

    expression of LXR target genes (Escajadillo et al., 2016). OSBP family modulates also vesicular transport. OSBP1 interacts with VAP-A protein, which is important for protein and lipid transport to the Golgi apparatus (Wyles et al., 2002). The depletion of OSBP1 causes changes in localization of intra-Golgi v-SNARE proteins (Nishimura et al.,…

  • Lipid Biochemistry

    lipids. Lipid transport can occur by various mechanisms (Fig.1a). First, lateral diffusion of lipids through membrane continuities, such as those that exist between the ER and the outer and inner nuclear membrane. Next, vesicular transport to the Golgi, the plasma membrane and endosomes, which is the major membrane transport pathway between cellular organelles in the secretory and endocytic pathways; through the budding and fusion of membrane vesicles. The uptake of fluorescent sphingolipid and…

  • The Four Components Of Cell Membrane

    As we all know and have been studying as scientist that the cell is the basic unit of life. The cell provides structure for the body, takes in nutrients from food, convert those nutrients to energy and carries out specialized functions. The cell is composed of many parts, all with different functions. The cell is made up of two major parts which include the nucleus and the cytoplasm. The nucleus is surrounded by a nuclear envelope, which can also be referred to as the nuclear membrane which is…

  • Unit 5 P5 Research Paper

    P5 List of all cell features and functions: • Nucleus • Cytoplasm • Cell membrane • Mitochondria • Ribosomes • Cell wall (Plant Cell) • Endoplasmic Reticulum (smooth & rough) • Lysosome • Golgi Apparatus/body • Nucleolus • Vesicles A nucleus is like the brain of the cell, it is a large oval which controls the activities of the cell and the nucleus also contains genetic material (DNA). The nucleus also contains hereditary information. Most chemical processes and reactions, which are…
