Question

as food travels through the digestive system, it is exposed to a variety of ph levels. the stomach has a ph of 2 due to the presence of hydrochloric acid (hcl), and the small intestine has a ph ranging from 7 to 9. hcl converts pepsinogen into pepsin, an enzyme that digests proteins in the stomach. which of the following most likely happens to pepsin as it enters the small intestine? it becomes inactive it begins to replicate it changes shape to engulf large proteins it increases energy exponentially type your first and last name for grading kyle hyatt the enzyme lactase will break down the sugar lactose into which of the following components? a. nucleotides

Explanation:

Enzymes like pepsin have an optimal pH for activity. Pepsin is active in the acidic stomach (pH 2). The small - intestine has a neutral to basic pH (7 - 9). A significant change in pH can denature the enzyme, making it inactive. Lactase breaks lactose into glucose and galactose, not nucleotides.

Answer:

First question: it becomes inactive
Second question: None of the options provided are correct as lactase breaks lactose into glucose and galactose.
