Vesicle

rough ER yet they are two completely different organelles. Its main function is to create complex molecules using numerous simple molecules that it has gathered from the cell. The Golgi apparatus is the organelle that creates lysosomes and other vesicles that are stored in the cell until they need to be used. It is unsure of where it evolves from but it is made of up a series of overlapping plate-like membrane, called…

Introduction Dyshidrotic eczema (pompholyx) is a type of eczema that causes very itchy (pruritic), fluid-filled blisters (vesicles) to form on the hands and feet. It can affect people of any age, but is more common before age 40. There is no cure, but treatment and certain lifestyle changes can help relieve symptoms. What are the causes? The cause of this condition is not known. What increases the risk? You are more likely to develop this condition if: You are older than 40. You are female. What…

pits. This is necessary for the LDL receptor to carry the bound LDL into the cells as these pits are the entrance into the cell (Goldstein and Brown, 1987). Soon after the clathrin coated pits form, they invaginate to for coated endocytic vesicles. The vesicles quickly shed their coats and fuse together with another becoming endosomes. Once in the endosomes, the LDL is released from the receptor due to the acidic pH. The acidic pH causes a conformational change in the LDL receptor which…

determine if one is larger than the other and presence of fluid in the larger one is a method that in less invasive and used often. There is also the palpation of the amniotic vesicle by “placing all four fingers dorsally and the thumb ventrally along the greater curvature of the horn”. After 60 days, the amniotic vesicle becomes flaccid which makes direct palpation of the fetus possible. Adapted nutrition is important in any gestating female. As for cows, their nutritional needs are similar to…

The axon is a neuron’s extension that sends messages to other neurons or to muscles or glands. It transmits the Impulse, aka the action potential. The axon terminal, or the terminal button is the end of the axon and it houses the synaptic vesicles, synaptic vesicles, and neurotransmitters which are the…

During pregnancy there are a lot of things you don’t know, like how what sperm is a girl and a boy and when you can find out. When you are pregnant there are many stages of fertilization. Which include the first, second, ad third trimester. This happens within the nine months of pregnancy. Sperm meets eggs. During the cycle one or two follicles release an egg and then it goes into the fallopian tube. One sperm will penetrate the egg and mix their genetic material. The sperm and egg contain 23…

The Influenza virus has genetic material inside the nucleus in order for the the virus to duplicate and make more copies that can infect humans or animals. There are spikes of protein molecules on the outer shell of the envelope that attack other cells with the virus. The ‘H spikes’ are used to infect other cells whereas the ‘N spikes’ are used to break away from the infected cells once copies are made to infect more cells. These “spikes” are known as protein molecules, hemagglutinin and…

Each Rab specifically targets to a membrane compartment and controls several factors, such as protein and lipid composition of the membrane, fusion between distinct compartments, vesicle motility along microtubules, and interaction with the cytoskeleton. The membrane targeting process, as well as specific binding to GDI, requires post-translational isoprenylation (geranylgeranyl moieties) of the two Cys residues at or near the C-terminus of Rab (Chavrier et al., 1991; Ullrich et al., 1993). √…

Reactive arthritis consists of the triad of arthritis, conjunctivitis, and urethritis known as Reiter’s syndrome. ReA commonly affects at aged 20-40 years by 1-4 weeks following a gastrointestinal or genitourinary infection. The manifestations of ReA are usually acute and present with fatigue, fever and malaise. Asymmetrical oligoarthritis is the main symptom, localized in the large joints of the knees, ankles and feet. 1 In 50% of the patients have low back inflammatory pain, worse during the…

It requires cellular energy. Eg ions, sodium, glucose and sugar. Types of active transport Bulk transport: Exocytosis: a vesicle containing the molecule fuses with the inside of the plasma membrane and the molecule is expelled. Endocytosis: The membrane recognises and binds with a molecule in its environment. The fluid membrane then forms a vesicle around the molecule, and the sac enters the cell. Phagocytosis and pinocytosis are examples of endocytosis. Passive transport is the movement…
