Female Mosquito Digestive Enzymes Essay -- Biology Aedes Aegypti

IntroductionMosquitoes argon remembered by most as being the torment of the discoverdoor barbecue the reason that bug zappers were invented. However, mosquitoes are not sincerely as bad as some people think. To begin with, mosquitoes are equal opportunity pests. They will go after(prenominal) anything with telephone line, not nevertheless human flesh. In fact, it is only the female mosquito who bites the male mosquitoes dont drink blood and are relatively innocent. Finally, mosquitoes are extremely well adapted to what they do. When a female mosquito bites an animal, certain chemicals in the animals blood tell her when she has hit a blood vessel. Then, the mosquitos specialized saliva kicks in to keep the wound from clotting. In this manner, a typical 2 mg. mosquito grass take in ii to three times its own weight in blood.Experiment one and only(a)When a mosquito takes in blood, it needs to be able to break the proteins in that blood down into their component amino acids in o rder to engage any nutrition from the meal. The gut of the mosquito employs a class of enzymes called proteolytic enzymes to get through this. Trypsin, the enzyme being studied in this project, is one such enzyme. It is separated into both categories early trypsin, which appears shortly after a blood-meal, and posthumous trypsin, which appears later in digestion, and which does most of the work of digestion. The project found evidence that early trypsin use (that is, the presence of early trypsin in the gut following a meal) was essential to the production of late trypsin later in the experiment. The early trypsin is present in small amounts about two hours after a meal, and the amounts fade out after about eight hours. At about twelve hours after the meal, the late trypsin begins to form. The early try... ...vel of late trypsin translated in relation to the amount of protein in the meal. Regulation at both the transcriptional and translational levels allows the mosquito to ad just the levels of late trypsin with noteworthy flexibility in response to a particular meal. In former(a) words, the mosquito has the ability to assess the quality of its meals and then appropriately synthesize the late trypsin gene. This tight regulation might be important in reserving the implication of late trypsin when it isnt needed.By studying trypsin (early and late) activity in the midgut of the mosquito it is possible that a mosquito contraceptive might be developed. A block of trypsin equates to no ballock and no offspring. Therefore, if we find a way to block trypsin production we can stop mosquitoes from reproducing greatly decreasing or even diminishing these infirmity carrying insects.
