Endoplasmic reticulum

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…

Peggy Fender is a 59 year old woman who appears to be an alcoholic as she has had many visits to the emergency department in the past. She arrives in the afternoon appearing intoxicated and complaining of abdominal pain in the right upper quadrant of her abdominopelvic cavity. As Tim, the physician assistant proceeds with his examination he notices bruising on her arms legs and face. She is jaundiced and he notices the smell of alcohol on her breath. In addition, her liver and entire abdomen are…

organelles – “tiny organs.” It’s only common sense that if you are able to relate things you learned in class to everyday things, you’ll remember it better. It’s not everyday that you and your friends sit around at Starbucks discussing the rough endoplasmic reticulum. However, you probably do discuss things like clothes, music, places to visit, etc… Therefore, your task in this assignment is to relate the different cell organelles to an everyday situation or thing using an analogy (a comparison…

Porter et al., 1945 using cells derived from chick embryos tissues with the aid of electron microscopy examined into detail the structural outline of the cell and organelles including: mitochondrion, Golgi Bodies and endoplasmic reticulum (Porter et al., 1945). This then created an avenue for enquiry into how these compartments within the cell interacts, how molecules move from one compartment to the other. In order to address concerns surrounding trafficking of substances through…

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…

To begin, the role of the ACH receptor is vital to biology. An incoming action potential to an alpha motor neuron causes acetylcholine or ACH, at the end plate. The ACH binds to ACH receptors on the sarcolemma causing a depolarization through sodium influx. In your body, calcium performs a number of basic functions. The body uses around 99 percent of its calcium to keep bones and teeth strong, as a result, supports skeletal structure and function. The rest of the calcium in your body plays…

Cell biology 1. A cell is eukaryotic because  Is generally larger and much more sophisticated than prokaryotic cells due to the presence of a complex series of membranes that divide a typical eukaryotic cell into compartment.  Eukaryotic cell has an organized nucleus with a nuclear envelop.  Has membrane bound organelles  Contain linear DNA molecule that are larger than the (circular) DNA molecules in prokaryotic cells and, in association with proteins, form structures called chromosomes.…

such as Legionella pneumophila. Macrophages ingest these bacteria in order to digest them, however, the Legionella pneumophila containing phagosomes (LCPs) avoid the lysosomes of the cell by replicating and converting the phagosome into an endoplasmic reticulum derived organelle with the aid of Sar1 and ADP-ribosylation (ARF). Sar1 and ARF are GTPases that control the production of the vesicles COPII- and COPI-. From there the bacterium attracts the host vesicles to bind to the membrane of…

uses cholesterol, including the liver cells that take them up too.2 Viruses hijack these lipoproteins and use them to get into the liver cells, where they replicate, which opens up a gateway to the rest of the body. They replicate within the endoplasmic reticulum and then use the lipid droplets as scaffolds. After budding off they’re still inside the liver cell where they either accumulate and burst the cell to be released or attach to a VLDL and get transported out. In addition to using…

significant and reflect a difference in the functions of each cell.Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements. The functions of these organelles are extremely similar between the two classes of cells (peroxisomes perform…
