1. Which hormone stimulates the gallbladder to contract?

Correct answer: B

Rationale: Cholecystokinin (CCK) is the hormone responsible for stimulating the gallbladder to contract and release bile into the small intestine. Secretin primarily acts on the pancreas to stimulate the secretion of bicarbonate-rich fluid. Gastrin functions in the stimulation of gastric acid secretion, while Gastric inhibitory polypeptide (GIP) plays a role in inhibiting gastric acid secretion and stimulating insulin release.

2. The mineral that helps control enzyme actions in cell mitochondria that produce and store high-energy compounds is:

Correct answer: A

Rationale: The correct answer is iron. Iron is essential for enzyme function and energy production within the mitochondria. While cobalt is important for certain enzymes, it is not the primary mineral involved in this specific function. Hemoglobin is a protein in red blood cells that carries oxygen, not a mineral involved in enzyme actions. Vitamin B12 is crucial for nerve function and DNA synthesis but is not directly related to controlling enzyme actions in mitochondria.

3. Which component of protein contains nitrogen?

Correct answer: A

Rationale: The correct answer is the amino group. Amino groups are functional groups found in amino acids, which are the building blocks of proteins. These groups contain nitrogen and are essential for the structure and function of proteins. The carboxyl group (choice B) contains carbon, oxygen, and hydrogen, while the peptide bond (choice C) is a covalent bond formed between amino acids in a protein chain. The side chain (choice D) refers to the unique chemical structure attached to the central carbon of an amino acid and varies among different amino acids, but it does not specifically contain nitrogen.

4. Which of the following sugars tastes the sweetest?

Correct answer: D

Rationale: Fructose is known to be the sweetest among naturally occurring sugars. While glucose, sucrose, and galactose also have sweet tastes, fructose is commonly perceived as the sweetest due to its higher level of sweetness. Glucose is a simple sugar found in many carbohydrates; sucrose is table sugar composed of glucose and fructose; galactose is a component of lactose found in dairy products. However, when comparing the sweetness levels of these sugars, fructose stands out as the sweetest.

5. The end products of digestion of macronutrients include fatty acids, amino acids, and:

Correct answer: A

Rationale: The correct answer is A: monosaccharides. When macronutrients like carbohydrates are digested, they are broken down into simpler forms. Carbohydrates are broken down into monosaccharides, proteins into amino acids, and fats into fatty acids. Therefore, the end products of carbohydrate digestion are monosaccharides. Choices B, C, and D are incorrect because polysaccharides are larger carbohydrate molecules, enzymes are not the end products of digestion but rather aid in the process, and cholesterol is not a direct end product of macronutrient digestion.
