1. Which organ produces and secretes bicarbonate ions and insulin?

• A. Stomach
• B. Pancreas
• C. Large intestine
• D. Small intestine

Correct answer: B

Rationale: The pancreas is the correct answer because it performs two vital functions: producing bicarbonate ions to neutralize stomach acid in the small intestine and secreting insulin to regulate blood glucose levels. The stomach is incorrect because its primary function is to break down and digest food, not produce bicarbonate ions or insulin. The large and small intestines are also incorrect because their primary functions are to absorb nutrients and water from food, rather than producing bicarbonate ions or insulin.

2. The Acceptable Macronutrient Distribution Ranges state that half of your calories should come from protein.

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: B

Rationale: The statement is FALSE. The Acceptable Macronutrient Distribution Ranges recommend that 10-35% of daily calories come from protein, not half. The remaining calories should be derived from a combination of carbohydrates and fats to ensure a balanced diet. Choosing option A is incorrect because it misinterprets the recommended percentage for protein intake. Options C and D are left blank as they are not applicable to the question.

3. Each of the following is a characteristic of fat, except one. Which is the exception?

• A. 95% of ingested fats are absorbed
• B. Hard fats take longer to digest than soft fats
• C. Fats contribute to palatability and flavor of foods
• D. Cooked fats improve the texture of foods

Correct answer: B

Rationale: The correct answer is B. Hard fats take longer to digest than soft fats because hard fats are solid at body temperature, making them more challenging to break down. Choice A is true as the majority of ingested fats are absorbed. Choice C is correct as fats indeed contribute to the palatability and flavor of foods. Choice D is accurate as cooked fats can enhance the texture of foods.

4. Low levels of physical activity are more commonly associated with which type of cancer?

• A. Esophageal cancer
• B. Pancreatic cancer
• C. Lung cancer
• D. Colon cancer

Correct answer: D

Rationale: Low physical activity is most strongly associated with an increased risk of colon cancer. Regular exercise helps regulate bowel movements and reduce inflammation, which are factors that can contribute to the development of colon cancer. Esophageal cancer, pancreatic cancer, and lung cancer are not as directly linked to low levels of physical activity.

5. Which of the following are absorbed into the bloodstream without needing additional digestion?

• A. amino acids
• B. monosaccharides
• C. glycerol
• D. all of the above

Correct answer: D

Rationale: Amino acids, monosaccharides, and glycerol are absorbed directly into the bloodstream without requiring further digestion.
