Final answer:
Patients with cystic fibrosis require pancreatic enzyme supplements to assist in digestion due to their compromised pancreas function. These supplements, including enzymes like trypsin and pancreatic amylase, must be taken with food to function properly in the less acidic environment of the small intestine.
Step-by-step explanation:
Cystic fibrosis affects the pancreas and alters the digestive process. In patients with cystic fibrosis, pancreatic enzyme supplements are necessary to aid in digestion. These supplements must contain a mix of enzymes including pancreatic amylase, trypsin, and lipase. Taking these supplements with every meal and snack is essential since they replace the enzymes that the pancreas of an individual with cystic fibrosis fails to deliver in the adequate amount or activity.
The enzymes are designed to be released in the small intestine, where they begin to break down food as part of the digestive process. The small intestine is coated with mucus to protect it from the active enzymes. Moreover, bicarbonate-rich pancreatic juices are crucial as they help neutralize acidic chyme and provide the optimal environment for enzymatic activity. Bicarbonate makes the environment less acidic, which is necessary for the enzymes to work properly. This process helps ensure that nutrients from the food are absorbed effectively in the intestine.
