Question

select the correct answer.
tascha is on a medication that increases the ph of the stomach and makes it alkaline. what is the effect of this medication?
a. the medication hampers bile production.
b. pepsin is unable to break down proteins.
c. stomach cells secrete more mucus to combat it.
d. lipase is unable to break down fats.
e. the medication hampers mechanical digestion.

Explanation:

Pepsin is an enzyme that breaks down proteins in the stomach, and it functions optimally in an acidic environment (low pH). If the stomach becomes alkaline (high pH) due to the medication, pepsin's activity is inhibited, so it can't break down proteins. Option A is incorrect as bile production is related to the liver/gallbladder, not stomach pH. Option C: Stomach mucus secretion is more related to protecting against acid, not alkaline conditions. Option D: Lipase (for fat digestion) mainly acts in the small intestine, not affected by stomach pH. Option E: Mechanical digestion (like churning) isn't directly affected by stomach pH change.

Answer:

B. Pepsin is unable to break down proteins.
