Microtubule

The chronic inflammation is slow onset reaction which needs days to start. However, once it is started, it is a long duration reaction and is associated with more tissue destruction. The reaction needs lymphocytes and macrophages, and the proliferation of blood vessels and the deposition of connective tissue are also existed in the response. What is more, it is lack of local and systemic signs and is always severe and progressive, and may causes tissue injury and fibrosis. While the acute…

Mitochondrion are made of two membranes. The outer membrane covers the organelle and acts as a layer of skin, whereas the inner membrane constantly folds over and creates layered structures called Cristae (The constant folding increases the surface area of the organelle). And the fluid inside the organelle is called the matrix. The matrix carry the specific DNA and ribosomes for the mitochondria, because the organelle carries its own DNA. Site of aerobic respiration and provides energy (ATP) to…

describe the whole class of proteins that had been found in a stratum corneum. (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2721001/) Filaggrin tends to associate with keratins, which take part in a formation of a scaffold. However, actin filaments or microtubules are not associated to filaggrin molecules. The synthesis of filaggrin begins with a large, insoluble precursor molecule, called profilaggrin, which can be found in stratum granulosum. During the cell maturation, profilaggrin is…

The simple definition of Eukaryotes is that they are any organism whose cells contain a nucleus and other membrane enclosed organelles. Taxonomically, Eukaryotes belong to the taxon Eukarya. The three types of eukaryotic microbes are fungi, protozoa, and algae. Because the three types of eukaryotic microbes are all composed of eukaryotic cells, they have basic similarities in cellular structure, including the presence of a nucleus. However, these types of microbes do differ in many significant…

It is contained by the nuclear membrane. The Nucleolus is found within the nucleus. It makes(or starts to make) the ribosomes used in making proteins. Microfilaments have pipe-like construction and provide the cell with support and structure. Microtubules are found in Cilia and Flagella and are tiny 'tube' structures that aid the cell is transporting particles around the cytoplasm. In a plant cell, the chloroplasts are plastids that have chlorophyll and are the location where photosynthesis…

The Cell Membrane is one of the most important parts of the cell. If not for the cell membrane it would be extremely easy for things to invade the cell; this is because on of the cell membranes job is to control what come in and out of the cell (i.e. ions, viruses, etc). Also the cell membrane is what helps hold the cell and all of its organelles Endoplasmic Reticulum (AKA the ER), smooth and rough whats the difference? The smooth ER does not have any ribosomes while the rough ER is covered in…

subgranular cell layer of the dentate gyrus, which are usually identified via BrdU staining, give rise to intermediate progenitors. These intermediate progenitors, in turn, create neuroblasts that express neuronal cell markers like DCX, which is a microtubule associated protein. These neuroblasts are hyperexcitable, and are known to activate and engage in long-term potentiation at lower thresholds for a given period of time compared to mature granule cells. Once these newborn neurons exit the…

Smooth Endoplasmic Reticulum The endoplasmic reticulum, or ER, is a network of flattened sacs and microtubules. The endoplasmic reticulum is very large and extends from the nuclear envelope to the cell membrane. The space inside of the endoplasmic reticulum is called the lumen. The smooth endoplasmic reticulum is called such because it doesn’t have ribosomes…

1. Why is the cell theory significant (don’t just state the tenets, explain what it means and why it is a theory)? The cell theory is significant because of it’s three basic ideals or principles. The first is that all organisms are made from cells. This means that cells are the building blocks of life and technically, all of life is connected and related to each other by this tenet. In addition, by researching and examine one type of cell, the results can be assumed for all similar types of…

Plasmodium is a parasite with over 100 species, but only four directly affect humans(“Malaria Parasites”). This parasite affects the circulatory system, or cardiovascular system(Coolidge-Stolz 78). Even though it’s microscoping in size, it can cause a lot of damage. It has many things that structure it, and some are even in common with animals (“Structure of Plasmodium Merozoite”). The parasite gets into the body from mosquitoes and infects the bloodstream(“Plasmodium”). The plasmodium parasite…
