The digestive juice product containing enzymes capable of digesting all four major foodstuff categories is:
a. Pancreatic
b. Gastric
c. Salivary
d. Biliary

검증된 단계별 안내

Step 1: Identify the four major foodstuff categories that need to be digested: carbohydrates, proteins, lipids (fats), and nucleic acids.

Step 2: Understand the role of each digestive juice listed: pancreatic juice, gastric juice, salivary juice, and biliary (bile) juice, focusing on which enzymes they contain and what substrates they act upon.

Step 3: Recall that pancreatic juice contains a variety of enzymes including amylase (for carbohydrates), proteases like trypsin and chymotrypsin (for proteins), lipase (for lipids), and nucleases (for nucleic acids), making it capable of digesting all four major foodstuff categories.

Step 4: Compare this with gastric juice, which mainly contains pepsin for protein digestion; salivary juice, which contains amylase for carbohydrate digestion; and biliary juice (bile), which emulsifies fats but does not contain enzymes to digest all categories.

Step 5: Conclude that the digestive juice capable of digesting all four major foodstuff categories is pancreatic juice.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Major Foodstuff Categories

The four major foodstuff categories are carbohydrates, proteins, lipids (fats), and nucleic acids. Understanding these categories is essential because different enzymes target specific macromolecules during digestion.

Digestive Enzymes and Their Sources

Digestive enzymes are biological catalysts that break down food molecules. Different digestive juices, such as pancreatic, gastric, salivary, and biliary secretions, contain specific enzymes that act on particular food types.

Role of Pancreatic Juice in Digestion

Pancreatic juice contains a variety of enzymes including amylase, proteases, lipase, and nucleases, enabling it to digest carbohydrates, proteins, fats, and nucleic acids. This makes it unique among digestive secretions for comprehensive digestion.
