What is insulin?
Soon after we eat, the beta cells in the pancreas secretes a hormone called insulin into the bloodstream to regulate glucose absorbed into the blood from digested food. It controls the entry of glucose into individual cells for fuel and also the way glucose is stored in fats cells as fat and in the liver as glycogen.
Insulin is a polypeptide hormone that regulates carbohydrate metabolism. [see figure for self explanation, courtesy endocrineweb.com] It is built from 51 amino acids and is one of the smallest proteins known.

Genetically modified organisms (GMO)
Pros and Cons of GMO Technology
Pros: Genetically Modified Organisms(GMO) can benefit and contribute to medicine in many ways. For example, there are genetically modified microorganisms that can make human insulin to treat diabetic patients. (3) There are genetically modified bacteria that can be used to clean toxic fuel and waste spills in the ocean. (4) Genetically modified plants are created to increase crop yields, reduced the need for pesticides, enabled pests and disease resistance to plants, and improve medical benefits. (4) Genetically engineered plants can allow them to grow faster, and resist most of the environmental elements, such as drought, frost, and other environmental factors. Other benefits of GMO are in the animals because fish like salmons have been genetically engineered to grow larger and faster. (4) Cattles have been genetically modified to exhibit resistance to mad cow disease. (4) Pharmaceuticals industry used geneticall modified organisms to make the first protein called the human growth hormone, which have been genetically engineered in plants. (4) Genetically modified animals are used to carry human genes that allow the study of them and their application to diseases. (4)
Other benefits of GMOs are to improve better taste, allowed faster outputs, and increased nutrients. (5) Farmers can also grow more crops on less land. (5) Farmers can produce more crops, such as genetically modified rice that have more vitamin A in them. (5 )Genetically modified rice can reduce vitamin A deficiency. (5)
There are disadvantage of introducing a new "expressed gene to change the natural state of an organisms." (4) The introduction of a foreign new gene to alter the natural genetic makeup of an organism can change the "organism's growth rate, metabolism, and response to external environmental factors." (4) The consequences of introducing a new gene to the organism can change the organisms itself and the natural environment in which the organism is allowed to live. (4) Human can be at risk of GMOs because the transfer of new modified gene to foods that we eat can introduce new harmful genes that make our system reject them. (4) For example, the "genetically modified Bt corn that expressed the protein from bacterium Bacillus thuringiensis", which is toxic to insects such as the caterpillar. The Bt corn that expresses this protein had reduced the amount of pesticides applied to the crops. But, the seeds of the corns containing the protein spread the recombinant genes to other nontarget plants and introduce toxic effects. The recombinant gene in bacteria such as E. coli can infect human and cause serious diseases. For example, the bacteria E.coli that carry "the tumor inducing gene from a virus" had infected human causing the disease. (4)View Full Posting Details
