than the original enzyme? 7. What is it called when Rubisco uses O2 instead of CO2, and why is this a problem? (The answer to this second question is not in the article, you should know this from the snow day class.) 8. How do the bacteria that normally use this enzyme compensate for its wastefulness? 9. Would you eat a (let’s say tomato) that contained this alternative enzyme? Explain why or why not. 10. Would you eat a tomato that has been treated with 1-MCP (the competitive

CASE STUDY #9 1. The organism that is causing this disease is Haemophilus influenzae. This bacteria is this because meningitis would mean the doctor believed the disease was an infection affecting the nervous system. All of the gram negative diseases that affect the nervous system are Haemophilus influenzae, Mycobacterium leprae, Neisseria meningitidis, and Treponema pallidum. The organism cannot be Neisseria meningitides because it has diplococci. Mycobaacterium leprae doesn't stain with gram

and doctors count stress, increase the acidity, lifestyle, and spicy food as main causes of gastric infection while others relate it to bacteria. The first belief was the most supposed until two Australian physicians, Barry Marshall and Robin Warren before 1982 when bacterium was discovered, proved the opposite. They built a theory based on a specific type of bacteria called Helicobacter pylori (H. pylori) as one of results of stomach infection and they proved it. Later, it has classified as one of

Phytochemical screening of the leaves extract All the solvent extracts were subjected to phytochemical screening and the results are presented in Table 1. Qualitative analysis of the leaf extract of A. muricata showed the presence of various phytochemicals. Methanolic extract of Annona muricata leaves showed the presence of alkaloids, flavonoids, coumarins, carbohydrates, glycosides, proteins, phenols, anthraquinones, steroids, phytosterols, cardiac glycosides and oil in the leaf. Carbohydrates,

viruses being live is that they lack most of the organelles necessary for biosythesis, thus reproduction. In order for a virus to reproduce it must find a suitable host. A virus is a bacteriophage, or intracellular parasite that multiplies inside a bacteria making use of the biosythetic organelles and structure that they lack. A virus expands through the mechanism of bacterial gene transfer.
