It could be due to not enough washing in the washing steps to remove nonspecific binding. 4. Briefly describe the basic structure of antibodies. Your answer: It is composed of four polypeptides linked by disulfide(-S-S-) bonds. The two heavy chains are about 400 amino acids long, and the two light chains about half that long.
The name is derived from the spongy holes that are only visible under a microscope that develop in the affected brain tissue. The risk of getting Creutzfeldt-Jakob disease is very low and usually affects people over the age of 60. It cannot be transmitted through coughing, sneezing, touching, or sexual contact. There are three ways that you can get Creutzfeldt-Jakob disease. You can get it spontaneously, and most
BIO 137 CASE STUDY#1 ANSWER SHEET Name Brookelyn Lail Section: J009 “Dangerously Thin: A Case Study on the Genetic Code” 1. Why would someone with this type of mutation be at a much higher risk for overdosing on a prescribed drug? The mutation causes the body to break down the medication faster than the body can handle resulting in overuse of the drug and easy overdose. 2. The underlying problem in this case resides in Henry’s “genes.” From what you know about the function of a gene, explain how this problem led to a malfunction in one of Henry’s proteins (the CYP2C9 enzyme).

12: Hydrolysis reactions ARE EXOTHERMIC 13: If a molecule is described as "organic," this means it CONTAINS CARBON AND HYDROGEN 14: Glucose is a sugar with six carbons. This makes it a HEXOSE Hexoses (sugars with six carbons), such as glucose, play a vital role in the metabolism of all cells. 15: A proton is an atomic particle with a POSTIVE CHARGE 16: Pasteur made major contributions to the study of which of the following? FERMENTATION 17: Which of the following is NOT associated with the structure of fats? PEPTIDE BONDS 18: Members of which of the following groups are
CL- 108mM eft & 10mM icf i. Ca2+ 1mM ecf & .0001 mM icf 15. How is the action of neurotransmitters terminated? w. Diffuse away from the synapse x. Inactivated by enzymes in the synapse cleft y. Transported back into the presynaptic cell or into adjacent neurons of glial cells 16. List four different types of glial cells, and briefly explain the role of each. z.
Gatorade showed negative results across the chart. As you will see we didn’t include sugar in this chart, which Gatorade tested extremely high in, as well as our other macromolecules. Unknown A, B, C, D are milk, tomato juice, ensure, and Gatorade respectively. As you can see from this chart, we tested sugars. Milk showed a moderate to high result in sugars, as for tomato juice showed a relatively low result for sugars.
Biochem Exam 3 Study Guide * What will be the product of pancreatic lipase?? Chapter 8 - Lipids How the fatty acids are denoted according to IUPAC nomenclature rules? # carbons: # double bonds … 18:2, cisΔ9,12 linoleic acid. Double bonds in fatty acids usually have the cis configuration. Each cis double bond causes a kink in the chain, or a bent tail.
SER lacks ribosomes and participates in lipid synthesis and detoxification. The Golgi apparatus is a system of membranous cisternae and vesicles arranged in stacks near the nucleus. The Golgi processes and modifies sugar side chains on proteins that are being secreted or destined for the plasma membrane or other membrane-bound organelles like the lysosome. Therefore, the Golgi apparatus is particularly prominent in cells synthesizing large
Cystic Fibrosis Cystic fibrosis is a hereditary disease, which is caused by the accumulation of mucus in epithelial cells of the digestive, respiratory, and reproductive tracts. Cystic fibrosis transmembrane conductance regulator (CFTR) facilitates chloride channel and controls several other metabolic pathways. Mutations in the particular gene cause cystic fibrosis. CFTR gene functions in regulating sweat, digestive juices, and mucus. A human body consists of two functioning CFTR gene, and when neither gene functions efficiently, cystic fibrosis is developed, and hence has autosomal recessive inheritance.
