ATI Nutrition Proctored Exam 2019 Answers
1. Which of the following is an example of a plasma protein?
- A. Collagen.
- B. Myosin.
- C. Albumin.
- D. Phospholipid.
Correct answer: C
Rationale: The correct answer is C, albumin. Albumin is a plasma protein that plays a crucial role in maintaining fluid balance in the blood. Collagen (choice A) is a structural protein found in connective tissues, not a plasma protein. Myosin (choice B) is a protein involved in muscle contraction, not found in the blood plasma. Phospholipid (choice D) is a type of lipid molecule, not a protein present in plasma.
2. What is the process by which proteins are synthesized from the available amino acids?
- A. Gluconeogenesis.
- B. Deamination.
- C. Protein synthesis.
- D. Transamination.
Correct answer: C
Rationale: The correct answer is C: Protein synthesis. This process involves the formation of proteins from amino acids to support various body functions. Gluconeogenesis (choice A) is the synthesis of glucose from non-carbohydrate sources, not protein synthesis. Deamination (choice B) is the removal of an amino group from an amino acid, not the synthesis of proteins. Transamination (choice D) is the transfer of an amino group from one molecule to another, not the direct synthesis of proteins.
3. What is necessary for photosynthesis to occur along with carbon dioxide and water?
- A. Glucose.
- B. Nitrogen.
- C. Chlorophyll.
- D. Hydrogen.
Correct answer: C
Rationale: The correct answer is C: Chlorophyll. Chlorophyll is a pigment that is essential for photosynthesis as it absorbs light energy, allowing plants to convert carbon dioxide and water into glucose, a process crucial for plant growth. Glucose (choice A) is produced during photosynthesis and is not an ingredient necessary for the process itself. Nitrogen (choice B) is important for plant growth but is not a direct ingredient for photosynthesis. Hydrogen (choice D) is found in water, which is indeed one of the necessary ingredients for photosynthesis, but chlorophyll is specifically required to capture light energy for the process to occur.
4. Which option below is an example of a meal or snack that contains complementary proteins?
- A. an egg and cheese omelet
- B. a peanut butter sandwich
- C. trail mix with nuts and raisins
- D. mixed bean salad with green beans, kidney beans, and white beans
Correct answer: B
Rationale: The correct answer is B, a peanut butter sandwich. A peanut butter sandwich combines grains from the bread and proteins from the nuts in the peanut butter, providing complementary proteins. This combination offers all essential amino acids. Choices A, C, and D do not contain complementary proteins as they lack the combination of different protein sources necessary to provide a complete amino acid profile.
5. Which of the following foods are major sources of starch?
- A. Fruits
- B. Meats
- C. Legumes
- D. Milk
Correct answer: C
Rationale: The correct answer is C: Legumes. Legumes, such as beans and lentils, are major sources of starch, providing complex carbohydrates. Fruits (choice A) mainly provide sugars rather than starch. Meats (choice B) and milk (choice D) are not significant sources of starch as they mainly provide protein and fats, respectively. Therefore, choices A, B, and D are incorrect.
