• If the protein doesn't fold properly or if it misfolds, the process results in disease. The misfolding of the protein PrPC turns to a harmful PrPSc. • PrPSc is hydrophobic and needs other cells so it changes other PrPC’s into PrPSc. • Eventually all of the PrPC’s are changed to PrPSc’s and aggregate together in the cell and ultimately kill the cell. • This cell death is what gives tissue the spongy like appearance known as BSE.
Chapter 22 skin infections * Skin infection - can kill you, mess with your bones, tissues, skin infection, heart valve infection, food poising * Staphylococcus aureus(staff) * Purple cluster spheres * Why is staff so pathogenic (disease causing) Pathogenic mechanisms of Staph.aureus * leukocidin * It kills your white blood cells * Coagulase - factor that makes your blood clot * With clotting white blood cells are not able to help fight off cause they are blocked * Protein A * They are Y shaped * Protein A binds to antibodies * They form by the ends off the tips off the top of the Y * Binds antibodies in the wrong direction so it will not trigger antibodies
This will lead to degradation of adenine nucleotides. This, then leads to concomitant hypoglycemia. This can lead to liver damage. The specific substrate acted on by adolase B is F1P (Fructose 1 phosphate). When the aldolase B is not functioning, we cannot process F1P, which causes an accumulation of F1P in the liver.
All forms of botulism can be fatal and are considered medical emergencies. Foodborne botulism is a public health emergency because many people can be poisoned by eating a contaminated food. What kind of germ is Clostridium botulinum? Clostridium botulinum is the name of a group of bacteria. They can be found in soil.
The water attached to the blood cells also, but it is eliminated from the body through sweat and urine from the kidneys. An enzyme is particles of protein that are created from chains of amino acid. They are formed inside of every organisms and plant that is alive. The body of the host determines the way the enzymes is utilized and the way it functions. That is the main reason a person’s body become disoriented when it’s in need of enzymes, the lack of enzymes throws the body functions out of whack (UIC, n.d.).
This system is called nucleotide excision repair and it is one of many systems that helps repair genes in the body. When it comes to Xeroderma Pigmentosum (XP) this is not the case, the nucleotide excision repair is not working in this disease, causing this persons DNA to stay damaged and has a phenotype with an OMIM number of 278700 (McKusik, 1986) . This disease is not only brutal to ones DNA but because their body cannot repair the DNA when exposed to UV light for even a minute it can have drastic affects. This disease was really described by two dermatologists from Vienna. They described the disease as xeroderma, which means parchment skin and then later added on the word pigmetnosum
The sexually transmissible disease gonorrhea has become increasingly resistant to treatment with antibiotics. What is the most likely scientific explanation? a) The gonorrhea bacteria learned to avoid antibiotics b) The gonorrhea bacteria changed their genes when they sensed antibiotics c) Antibiotic-sensitive gonorrhea bacteria died out, but antibiotic-resistant gonorrhea bacteria have flourished and persisted d) The antibiotic increased the mutation rate in the gonorrhea bacteria e) Both b and d 26. Which statement best describes the relationship between plants and animals on earth? a) Plants produce O2 and sugars from CO2 b) Animals produce CO2 and H2O from sugars and O2 c) Plants produce O2 and sugars and animals produce CO2 and H2O d) Animals produce O2 and sugars and plants produce CO2 and H2 27.
This deletion causes the amino acid phenylalanine to be removed. Normally, after CFTR has been synthesized, it is moved to the endoplasmic reticulum and Golgi apparatus for final modifications before it becomes incorporated into the cell membrane. However, in patients with cystic fibrosis, when the defective CFTR protein reaches the endoplasmic reticulum and Golgi apparatus, it is unrecognizable because the protein has been folded improperly. As a result, the effectiveness of the
The myelin sheath around the axon of the brain and the spinal cord are damage. MS prevent the nerve cells of the brain and the spinal cord from affectivity communicating by slowing down the nerve impulse. When the electrical nerves slow down, its blocks a signal from being passing from the brain to the spinal cord, result in a lost connection. MS is an auto immune system disease when the body destroys itself. The immune system work against the body a foreign virus enters the body; the body make antibodies to fight of the infection, but the immune system eventually work against itself by helping to destroy the myelin around the axons.
BSE arise spontaneously in cattle and once human digest the cows infected meat, the disease mutates into its human version called Creutzfeld Jacob Disease(CJD). CJD has been found in people who ate infected beef products. It is Fatal and
