Biology Summer Task Our digestive systems contain glands. These glands produce enzymes. Enzymes are catalysts. Catalysts make chemical reactions happen quicker and easier. Digestive enzymes help us to break down food easier. Our bodies make lots of different digestive enzymes. Each enzyme breaks down a particular food. When an enzyme has broken down one food molecule‚ it can then break down another molecule of the same kind. It can do this over and over again. It makes the reaction happen without

The digestion process The digestion process begins in the mouth. First we take a bite of food. The presccence of food in the mouth stimulates the flow of saliva from the salivary glands. Saliva moistens the food and carries dissolved food molecules to the taste buds. Saliva helps digest food because it contains enzymes that start to break it down. After the food is covered with saliva‚ you then begin to chew your food. Chewing breaks down food into smaller pieces and also breaks apart fiber that

The assignment that I learned the most from was the Week Two assignment about the digestive system. I now understand how the body uses the different types of food‚ the path food takes as it enters the body‚ and how the organs‚ including the salivary glands work together in the digestive process. However‚ my favorite part of Week Two came through the class discussions in the area of home remedies. I learned how a change in diet can prevent or help to cure digestive disorders. For example‚ Diverticulus

Genetically Modified Organism is the purpose to improve or correction of defects‚ by changing one’s genetic make up and adjusting the DNA ("Animal Biotechnology | Bioscience Topics | About Bioscience"‚ 2006). This type of technology has been experimented on what is called the Enviropig‚ invented which manupilates the genes to help produce less phosphorus in its manure‚ this is more efficiently than conventional Yorkshire pigs. The feces from the Yorkshire pigs were discovered that it contained large
