Bile is a secretion which aids in the digestion of

Answer Explanation

A) there is a malfunction with the digestive system

- Correct: Inability to break down food particles into molecules that can be absorbed by the body suggests a malfunction with the digestive system. The digestive system is responsible for the mechanical and chemical breakdown of food into smaller molecules, such as carbohydrates, proteins, and fats, that can be absorbed by the intestines and utilized by the body for energy, growth, and repair. If the digestive system is not functioning properly, it can lead to malabsorption of nutrients, resulting in nutritional deficiencies and related health issues.

B) there is a malfunction with the excretory system

- Incorrect: The excretory system is responsible for removing waste products from the body, primarily through the kidneys, urinary tract, and skin. While the excretory system plays a role in eliminating some metabolic waste products generated from the breakdown of nutrients, it is not primarily responsible for the breakdown of food particles into absorbable molecules.

C) there is a malfunction with the reproductive system

- Incorrect: The reproductive system is responsible for the production of gametes (sperm and eggs) and the facilitation of reproduction. It is not directly involved in the breakdown and absorption of food particles in the digestive process.

D) there is a malfunction with the circulatory system

- Incorrect: The circulatory system, comprising the heart, blood vessels, and blood, is responsible for transporting nutrients, oxygen, and other substances throughout the body. While the circulatory system transports nutrients absorbed by the digestive system to various tissues and organs, it does not directly participate in the breakdown of food particles into absorbable molecules.

Answer Explanation

D) vitamins and minerals

- Correct: Vitamins and minerals are nutrients that can be absorbed without first being digested in the human gastrointestinal tract. Unlike carbohydrates, proteins, and fats, which require enzymatic digestion to break them down into smaller molecules for absorption, vitamins and minerals are already in a form that can be readily absorbed by the body. Once absorbed, vitamins and minerals play essential roles in various physiological processes, such as metabolism, immune function, and bone health.

A) carbohydrates and polypeptides

- Incorrect: Carbohydrates and polypeptides (large protein molecules) require enzymatic digestion to break them down into simpler molecules (such as glucose from carbohydrates and amino acids from polypeptides) before they can be absorbed by the gastrointestinal tract.

B) proteins and vitamins

- Incorrect: Proteins require enzymatic digestion to break them down into amino acids before they can be absorbed by the gastrointestinal tract. While vitamins do not require digestion and can be directly absorbed, proteins do not fall into this category.

C) minerals and polysaccharides

- Incorrect: Minerals, such as calcium, iron, and zinc, can be directly absorbed without prior digestion in the gastrointestinal tract. However, polysaccharides (complex carbohydrates) require enzymatic digestion into simpler sugars before they can be absorbed.

Answer Explanation

The enzymes secreted by the pancreas play a crucial role in the digestion process by breaking down various nutrients, such as carbohydrates, proteins, and fats, into smaller molecules.

These smaller molecules are then absorbed through the walls of the small intestine into the bloodstream and subsequently transported to cells throughout the body for energy production, growth, and repair.

Therefore, these enzymes are essential for converting complex food substances into molecules that can be utilized by the body's cells for various metabolic processes.
