A2: 1. Mouth: The mouth starts mechanical digestion with the chewing that takes places there but also mixes amylase that is secreted from the salivary glands in with what is being chewed to start chemical digestion.(2) 2. Esophagus: The esophagus transfers food from the mouth to the stomach. (2) 3. Stomach: The stomach mixes various enzymes and chemicals that cause digestive breakdown of food stuff. (2) 4. Liver: The digestive function of the liver is to produce bile. (3) 5. Gallbladder: The gallbladder stores bile when there is no food to be digested and releases the bile into the duodenum when fatty foods enter it. (3) 6. Pancreas: The digestive function of the pancreas is to produce enzymes that breakdown all types of digestible foods. A3: Mechanical digestion is the act of physically breaking down food into smaller pieces to aid with chemical digestion. Chewing is an example of mechanical digestion. Chemical digestion is the process where enzymes are introduced into the gut, where it mixes with the food there. The food is at that time, broken down to the molecular level allowing the body to absorb the nutrients for use throughout the body. A4: 1 – Amylase 2 – Lipase 3 – Pepsin 4 – Nucleases 5 – Lactase 6 – Trypsin A5: Research of experiments previously performed can be invaluable when one is looking to design their own experiments to perform. This particular case is no exception. While attempting to come up with an experiment I researched many others and below are brief summaries of two such experiments. The first of these two is an experiment that was performed to show how specific enzymes perform at varying pH levels entitled “Effect of pH on Enzyme Activity”. The idea of the experiment is to record the reaction time of chicken liver enzymes when exposed to varying pH level solutions containing hydrogen peroxide.
