Question
Initial triglyceride, carbohydrate, and polypeptide digestion is performed by:A.lingual lipase, salivary amylase, and trypsinogen, respectively.B.bile, pancreatic amylase, and pepsin, respectively.C.bile, pancreatic amylase, and trypsinogen, respectively.D.lingual lipase, salivary amylase, and pepsin, respectively.
Solution
The initial digestion of triglycerides, carbohydrates, and polypeptides is performed by lingual lipase, salivary amylase, and pepsin, respectively. So, the correct answer is D. lingual lipase, salivary amylase, and pepsin, respectively.
Here's why:
-
Lingual lipase: This enzyme is secreted by the salivary glands in the mouth and it begins the process of triglyceride digestion.
-
Salivary amylase: This enzyme is also secreted by the salivary glands and it begins the process of carbohydrate digestion by breaking down complex carbohydrates into simpler sugars.
-
Pepsin: This enzyme is secreted by the stomach and it begins the process of polypeptide digestion by breaking down proteins into smaller peptides.
