Question
This assignment is meant to help you review the process of digestion and absorption of macronutrients. Jake loves Hot Pockets and eats at least 3 per day. His Hot Pocket® of choice is pepperoni pizza. As Jake eats and digests his Hot Pocket®, track the mechanical and chemical processes occurring in the Gl tract 1. Choose one of the three macronutrients (CHO, protein, or fat) to follow for digestion. Record this on the line below. List the components of the hot pocket that contain your micronutrient (breading cheese, pepperoni, etc.) 2. Label the GI tract diagram on the right. Note: this is a cartoon drawing and not drawn to scale. 3. Track digestion from the time the hot pocket enters Jake's mouth. Include the key accessory organs involved and what functions they play in the process. Where is your macronutrient absorbed? Be sure to mention what is happening, if anything, in the lower part of the GI tract 1. MACRONUTRIENT Components of Hot Pocketo that contain your macronutrient: 2. Label the GI tract diagram. 3. Track digestion of the Hot Pocket components in each section of the Gl tract. Be sure to indicate what is happening in the lower part of the GI track. Start with the mouth. Mouth:Explanation / Answer
1. Macronutrient selected - Protein
Components of hot pockets that contain this macronutrient - Cheese and Pepperoni
2. Lbelling of GI tract - MOUTH, ESOPHAGUS ( first rectangle), Stomach( circle), Small Intestine and Large Intestine( 2nd long rectangle) and Rectum(last small reactangle)
3. Digestion of Protein in the GI tract. - Cheese and Pepperoni after being chewed and mixed with saliva are propelled into the stomach. Here the breakdown of protein occurs by enzyme called Pepsin, HCl and Rennin. The ezymes Chymotrpsin and Trypsinogen then break down the polypeptide bonds of the protein to convert them into amino-acids. The amino-acids are then absorbed by Illuem or small intestine. Lower part of the GI tract helps in absorption of the nutrients, water and then expulsion of the waste material.
