Hardened deposits of cholesterol that accumulate in the structure that stores bile are known as

A. gallstones

B. ulcers

C. goiters

D. allergies

Answer Explanation:

A) gallstones

- Correct: Hardened deposits of cholesterol that accumulate in the structure that stores bile, which is the gallbladder, are known as gallstones. Gallstones can also contain other substances, such as bilirubin or calcium salts, in addition to cholesterol. These stones can vary in size and may cause symptoms such as abdominal pain, nausea, and jaundice. In severe cases, gallstones may require medical intervention, including surgery, to remove them.

B) ulcers

- Incorrect: Ulcers are sores or lesions that develop in the lining of the digestive tract, commonly in the stomach (gastric ulcers) or the upper part of the small intestine (duodenal ulcers). They are not related to hardened deposits of cholesterol in the gallbladder.

C) goiters

- Incorrect: Goiters are abnormal enlargements of the thyroid gland in the neck. They can be caused by iodine deficiency, thyroid disorders, or other factors, but they are not related to gallstones.

D) allergies

- Incorrect: Allergies are immune responses to specific substances (allergens) that the body perceives as harmful, leading to symptoms such as sneezing, itching, or anaphylaxis. They are not related to hardened deposits of cholesterol in the gallbladder.

Therefore, the Correct Answer is A.

  • Q #1: If a person was unable to break down food particles into molecules that could be absorbed by the body, you would predict

    A. there is a malfunction with the digestive system

    B. there is a malfunction with the excretory system

    C. there is a malfunction with the reproductive system

    D. there is a malfunction with the circulatory system

    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.

  • Q #2: What occurs during the digestion of proteins?

    A. Specific enzymes break down proteins into amino acids.

    B. Specific hormones break down proteins into simple sugars.

    C. Specific hormones break down proteins into complex starches.

    D. Specific enzymes break down proteins into simple sugars.

    Answer Explanation

    A) Specific enzymes break down proteins into amino acids.

    - Correct: This is the correct answer. Proteins are broken down into their constituent amino acids by specific enzymes during the process of digestion. Enzymes like pepsin in the stomach and various proteases in the small intestine facilitate this breakdown.

    B) Specific hormones break down proteins into simple sugars.

    - Incorrect: Hormones are not directly involved in breaking down proteins into simple sugars. Hormones are signaling molecules that regulate various processes in the body, including metabolism, but they don't directly participate in the breakdown of proteins into sugars.

    C) Specific hormones break down proteins into complex starches.

    - Incorrect: Hormones do not break down proteins into complex starches. Proteins are broken down into amino acids by enzymes, not hormones. Starches are complex carbohydrates and are broken down into simple sugars by enzymes like amylase, not proteins.

    D) Specific enzymes break down proteins into simple sugars.

    - Incorrect: Proteins are not broken down into simple sugars. They are broken down into amino acids by specific enzymes. Simple sugars come from the breakdown of carbohydrates, not proteins.

  • Q #3: Glycogen is best described as a

    A. complex carbohydrate that is often stored in red blood cells

    B. complete protein necessary for the synthesis of cell membranes

    C. polysaccharide that is synthesized and stored within the human liver

    D. by-product of sucrose digestion within the pancreas

    Answer Explanation

    C) polysaccharide that is synthesized and stored within the human liver

    - Correct: Glycogen is a polysaccharide, which means it is a complex carbohydrate composed of many glucose molecules linked together. It is synthesized and stored primarily in the liver and muscles of humans and other vertebrates. Glycogen serves as a form of energy storage, allowing organisms to store glucose for later use when energy demands are high or when glucose availability is low.

    A) complex carbohydrate that is often stored in red blood cells

    - Incorrect: While glycogen is a complex carbohydrate, it is not stored in red blood cells. Red blood cells do not contain nuclei or organelles, including glycogen storage structures.

    B) complete protein necessary for the synthesis of cell membranes

    - Incorrect: Glycogen is not a protein. It is a carbohydrate used for energy storage. Proteins are composed of amino acids and are involved in various cellular functions, including the synthesis of cell membranes, but glycogen does not play a direct role in this process.

    D) by-product of sucrose digestion within the pancreas

    - Incorrect: Glycogen is not a by-product of sucrose digestion within the pancreas. Sucrose is a disaccharide composed of glucose and fructose, and it is broken down into its component sugars by enzymes in the small intestine, not the pancreas. Glycogen is synthesized and stored in the liver and muscles as a form of energy storage.
