Niemann-Pick disease is a condition that affects many body systems. It has a wide range of symptoms that vary in severity. Niemann-Pick disease is divided into four main types: type A, type B, type C1, and type C2. These types are classified on the basis of genetic cause and the signs and symptoms of the condition. Infants with Niemann-Pick disease type A usually develop an enlarged liver and spleen (hepatosplenomegaly) by age 3 months and fail to gain weight and grow at the expected rate…
Eukaryotic cells are cells whose nucleus is bound by a membrane; these cells contain organelles, which are structures each enclosed within its own membrane found only in eukaryotic cells, each organelle has a specific function inside a cell. One type of organelle is a lysosome, which are the organelles that dispose of waste and toxins. Lysosomes are fluid filled sacks which range in size from 0.1 to 1.2 micrometres and contain around fifty degradative enzymes that enable it to effectively…
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…
It was time to depart. The engines had been warmed up, the supplies were ready and the equipment had been installed and was ready to use. “Five, four, three, two, one, BLAST-Off” chanted Captain Xerox at headquarters, and with that our micro-V96 craft was propelled towards the cell membrane for the first leg of our journey to investigate the process of Protein Synthesis in a eukaryotic animal cell. The cell membrane is a delicate wall of phospholipid molecules, consisting of hydrophilic heads…
When I was younger, I did trampoline and tumbling for seven years! Trampoline and tumbling is similar to gymnastics, however, the events were different. The events for trampoline and tumbling are trampoline, rod floor, as well as the double mini. Rod floor is about the width of a bed, and the length of at least 500 feet. In the middle of the floor is a straight line that you are required to stay on. A double mini is similar to vault however, rather than leather, it is a trampoline. I performed…
with four fire stations. The first city owned forestation was Engine Company No. 1 and was established in 1887. Into the early 20th century the Department began to fully expand its operations such as improved membership benefits, use of motorized apparatus, creation of the Mountain Patrol, and the implementation of the Emergency Medical Service System. In 1915, the Department changed over to a two-platoon system, requiring members to work a 12-hour day or 12-hour night shift for a total of…
Within the skeletal muscle cells, there are many organelles. Each cell contains a plasma membrane called the sarcolemma, covering the outer surface of the cell (Ivy Rose). The sarcolemma protects the muscle cell and allows for its shape to be kept. From the sarcolemma, tunnel-like extensions called transverse tubules pass through the muscle fiber (Ivy Rose). These transverse tubules connect the sarcoplasmic reticulum with the sarcolemma (Graham and Parker 117). The sarcoplasmic reticulum is a…
A. The cell membrane is made up of phospholipids, cholesterol, proteins, and carbohydrates. The phospholipids and cholesterol both help create the roof of the cell membrane and they both regulate the fluidity of the cell membrane. The proteins in the cell membrane help provide a structural function, transport function, and signaling function all within the membrane (Yeagle, 1989). The carbohydrates are on the external side of the cell membrane. Also the carbohydrates provide a signaling function…
Lens Fiber Differentiation and its effects on certain organelles. This writing exercise analyzes two separate but related scientific articles, “The fate of the Golgi Apparatus and the Endoplasmic reticulum During Lens Fiber Cell Differentiation” and “Coincident Loss of Mitochondria and Nuclei During Lens Fiber Cell Differentiation” both which analyze and study Lens Fiber Differentiation. The writing assignment will be based on four sections:(1) Background of the research (2) Methods used…
Cells have specific structures within them that allow them to carry out their functions; these structures are called organelles. Organelles have different functions within a cell that is called Division of Labor. They are also classified in two different groups, membranous and non-membranous. Membranous organelles are surrounded by a membrane while of course, non-membranous are not surrounded by a membrane. When describing the organelles and their function, first will be the membranous…
