Introduction:
The gastroesophageal reflux (GERD) disease is known to be a digestive disorder, which mainly affects the lower segment of esophageal sphincter, which is basically the ring of muscle found between the stomach and esophagus. The condition when the pH (potential of hydrogen) of esophagus drops below 7, the reflux is said to take place.

Carbohydrates and lipids are composed of the same chemical elements, but in different proportions. Both are used as energy sources for cell metabolism. Which type of molecule has the higher calorie content per gram. Explain..
In a hospital laboratory, a 10.0 mL sample of gastric juice, obtained several hours after a meal, was titrated with 0.01 M NaOH to neutral pH of 7.0; 72.0 mL of NaOH was required for this titration. The patient’s stomach contained no ingested food or drink, thus assume that no buffers were present.
What was the pH of the 10.0 mL gastric juice sample before titrating with NaOH?
Estimate the optimum pH for the digestive enzyme trypsin, which hydrolyzes proteins in the small intestines, from the following graph.

- The pH of human stomach acid ranges from 1.0 to 3.0, whereas a healthy esophagus has a pH of approximately 7.0. In gastroesophageal reflux disease (GERD), often called acid reflux, stomach acid flows backward from the stomach into the esophagus. Repeated episodes in which esophageal pH goes below 4.0, considered clinical acid reflux, can result in bleeding ulcers and damage to the esophageal lining. The data in the Figure, from a patient with GERD, show esophageal pH during a sleeping reflux event. How many minutes does it take to go from the peak of the reflux event (when pH is most acidic) to when the reflux event is over? Source: Based on T. Demeester et al. 1976.

- In the course of a hypothetical meal, the stomach expands from 0.25 liters to 1.25 liters.

- Drugs are small molecules that often occur in either a neutral or a charged form, depending on pH. For example, aspirin can be either neutral or lose a proton to be negatively charged. When aspirin is charged, it does not diffuse well into the body. pH varies in the gastrointestinal track. Since the stomach has a low pH (pH=3), it has a larger concentration of neutral aspirin (10-3 M), while the small intestine (pH=6) has a smaller neutral aspirin concentration (10-6 M). For the following, assume that the neutrally charged aspirin molecule has a diffusion coefficient through the cell of 1 x 10-6 cm2/s.arrow_forwardDrugs are small molecules that often occur in either a neutral or a charged form, depending on pH.

For the following, assume that the neutrally charged aspirin molecule has a diffusion coefficient through the cell of 1 x 10-6 cm2/s. C) We’d like to figure out where in the body aspirin is absorbed as determined by its diffusion rate. If the small intestine has a surface area 50 times that of the stomach, what is the ratio of the diffusion rates in the stomach compared to the small intestine? D) In which part of the GI tract is most of the aspirin absorbed?arrow_forwardConsider the scenario below: A 40-year-old woman was rushing to get to her workplace before office time.
