1. Each statement is true of proteins, except one. Which is the exception?

• A. Proteins are composed of building blocks called amino acids
• B. The classification of the 20 common amino acids is based on the properties of their side chains
• C. The general structure of an amino acid varies considerably
• D. Amino acids polymerize to form long chains called polypeptides

Correct answer: B

Rationale: The correct answer is B. The classification of the 20 common amino acids is not based on the properties of their side chains, but rather on the structure of their amino and carboxyl groups. These groups are consistent among all amino acids, while the side chains, also known as R groups, are what vary and give each amino acid its unique properties. Choice A is correct because proteins are indeed composed of amino acids. Choice C is incorrect because while the side chains of amino acids can vary, the general structure of an amino acid - a central carbon atom bonded to an amino group, a carboxyl group, a hydrogen atom, and a side chain - is consistent. Choice D is correct because amino acids do polymerize to form long chains called polypeptides, which can then fold into complex shapes to form proteins.

2. Bones continuously lose and gain minerals. This ongoing process is called?

• A. reorganization
• B. reorienting
• C. demineralizing
• D. remodeling

Correct answer: D

Rationale: The correct answer is D, 'remodeling.' Remodeling is the process by which bones continuously lose and gain minerals, maintaining bone strength and integrity over time. 'Reorganization' (choice A), 'reorienting' (choice B), and 'demineralizing' (choice C) do not accurately describe the process of bones continuously losing and gaining minerals.

3. Which is NOT a classification of carbohydrate?

• A. Monosaccharides
• B. Disaccharides
• C. Polysaccharides
• D. Triglycerides

Correct answer: D

Rationale: The correct answer is D, Triglycerides. Triglycerides are a type of fat, not a carbohydrate. Monosaccharides, disaccharides, and polysaccharides are all classifications of carbohydrates based on the number of sugar units they contain. Monosaccharides are the simplest form with one sugar unit, disaccharides contain two sugar units, and polysaccharides have multiple sugar units linked together.

4. What food assistance program provides a food debit card for older adults with low incomes?

• A. the OAA Nutrition Program
• B. Meals on Wheels
• C. the Supplemental Nutrition Assistance Program
• D. the Emergency Food Assistance Program

Correct answer: C

Rationale: The correct answer is C: the Supplemental Nutrition Assistance Program (SNAP). SNAP provides a food debit card to assist low-income individuals, including older adults, in purchasing food. Choice A, the OAA Nutrition Program, is incorrect as it refers to a different program specifically focused on providing nutrition services to older adults. Choice B, Meals on Wheels, is incorrect as it is a meal delivery service for homebound individuals rather than a food debit card program. Choice D, the Emergency Food Assistance Program, is incorrect as it typically involves the distribution of emergency food supplies rather than providing a food debit card.

5. Without enough calcium, both males and females are at risk of osteoporosis.

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: A

Rationale: The statement is true. Both males and females are at risk of developing osteoporosis if they do not consume enough calcium. Calcium is essential for maintaining strong bones, and inadequate intake can lead to bone density loss and increase the risk of osteoporosis. Therefore, it is crucial for individuals of all genders to ensure they have an adequate calcium intake to support bone health. Choice B is incorrect because osteoporosis is a condition that can affect both males and females.
