Experiment 13: How Much Stomach Acid Can Antacids Neutralize? PREPARATION WORKSHEET Name: 4 aaa Haas TA: Date: 9AM Section Answer the following questions using information obtained from lecture, the textbook, the lab manual, or other reliable sources. The responses will be collected at the beginning of Pre-Lab Recitation and checked at the start of your lab section for credit. Failure to complete all answers may result in exclusion from participating in the lab. 1. For each of the following food types, list where digestion is initiated and what enzymes are used to hydrolyze them. a. carbohydrates:-ni[A-ted mou,th b. proteins: C. lipids: 2. How does the pH of the stomach change when eating versus not eating? 3. In two or three complete sentences, describe what heartburn is and how antacids work to chemically counteract heartburn 223 an

Explanation / Answer

Q1

a)

carbohydrate digestion starts in the mouth, with saliva, having enzymes which start working onf complex carbohydrate breaking chains

b)

protein digestion starts in the stomach.the other step is in the duodenum

c)

lipid digestion starts in the mouth, followed by stomach, then small intestine

Q2

pH starts to decrease, when we do NOT eat, the excess hydrochloric acces is accumulated, so the pH must decrease in the stomach due to excess acid

Q3

heartburns are essentially gastric/stomach acids going back througth the esofagus. They will "chemically burn" our tissues, it is a c hemical burn, since HCl is a strong acid.

We use antacids to neutralize excess HCl rpesent. Those antacids are typically MgCO3, or CaCO3, which form H2O, CO2 and the respectivel chloride salt
