In 1993 there where several people that died of respiratory distress that was later diagnosed as Sin Nombre which was caused my Hantavirus from the Bunyaviridae family. This took place at the four corners where Arizona, New Mexico, Utah and Colorado meet. They determined that deer mice were the culprits and that Sin Nombre causes Hantavirus Pulmonary Syndrome (HPS). It is believed those that come in contact with urine, feces or saliva of the infected rodents will become ill. Infection can come
Protein Sorting In Endoplasmic Reticulum Background Cell division in a eukaryotic cell comprises of a series of complex process that ultimately lead to new daughter cells. While the cell undergoes division all the organelles have to undergo duplication so that they can be passed onto the daughter cells. The cell needs information from old organelles to synthesize new organelles. This process takes place during cell division, when the old organelles increase in size (enlargement occurs), due to

The two cells , membrane is made of phospholipids. Eukaryotic cells have a membrane channels almost like a transportation way within the cell which is called the endoplasmic reticulum. Within the eukaryotes are smooth endoplasmic reticulum without ribosomes. The rough ER is rough because it contains ribosomes. The golgi body inside the eukaryotic cells job is to transport proteins from the RER to the cell membrane to export. Lysosomes are digestive
membrane. The endoplasmic reticulum (ER) serves a selection of functions in the cell and is made of a network of tubules and flattened sacks. There are two sections if the endoplasmic reticulum called the rough endoplasmic reticulum and the smooth endoplasmic reticulum. The rough ER has ribosomes on the cytoplasmic side of the membrane which is why it is called the rough ER whereas the smooth ER lacks the attached ribosomes. Usually the rough ER is a series of flattened sacks whereas the smooth ER is a
Cardiac VS Skeletal Muscle Where are they found in the body? Cardiac muscle is found only in the heart and skeletal muscle is attached to bones which forms the skeleton to be used for movement. What is the structure? Cardiac and skeletal muscle is both striated (striped). Skeletal muscle tissue is composed of individual muscle cells known as muscle fibres or myocytes, within each myocyte there is myofibrils which help in muscle contraction. Skeletal muscle is made up is long and cylindrical in shape
organellar substructure that includes :- a) Numerous mitochondria : to generate energy by fatty acid oxidation and oxidative phosphorylation b) The endoplasmic reticulum. c) Lysosomes : contain proteolytic enzymes. d) The smooth endoplasmic reticulum. e) The rough endoplasmic reticulum. f) The multifunctional Golgi complex. g) Microtubules and microfilaments, [7]. 1.3 Functions of Liver: 1) Hepatic Excretory Function
I used to think that cells we boring, but that was before I went to school on Saturday, before I got trapped in one and before a evil scientist captured me. It all started this morning, I woke up and as usall got ready for school. I entered the class and saw Mr. FluffySnuff writing something on the board, I approached him and it looked like he was writing PLAN THE ELIMINATE ALL CHILDREN. I decided that i should go tell the principle, I backed away slowly and carefully hoping to get out the door
INTRODUCTION TO HUMAN BIOLOGY The cell is a small unit of life. Eukaryotic and prokaryotic cells are similar in a way that both contain cytoplasm. The cytoplasm is a jelly-like substance containing organelles such as ribosome and chemical called enzyme. Ribosome are protein synthesis, they are “made of RNA and protein but bacterial ribosome are smaller compared to the ribosome in the eukaryotic cell”. Both the eukaryotic and prokaryotic cells have a plasma membrane that regulates the flow of substances
active. The more mitochondria the more the muscle has energy. Cardiac muscle also has myoglobin, this organelle binds and stores oxygen for muscle cells to use. Skeletal muscle has an organelle called sarcoplasmic reticulum, this works in a similar way to smooth endoplasmic reticulum but the function is to store calcium ions, these are critical for muscle
