1. How many kilocalories (kcal) are provided by 35 g of fat?

Correct answer: C

Rationale: Fat provides 9 kcal per gram, so 35 grams of fat provides 315 kcal. Therefore, the correct answer is C. Choice A (140) is incorrect because it doesn't consider the energy content of fat. Choice B (245) is incorrect as it miscalculates the kilocalories provided by 35g of fat. Choice D (360) is incorrect because it overestimates the kilocalories provided by 35g of fat.

2. Proteins from plant sources such as grains, nuts, and legumes are classified as:

Correct answer: A

Rationale: The correct answer is A: 'incomplete.' Proteins from plant sources like grains, nuts, and legumes are considered incomplete because they often lack one or more essential amino acids required by the body. Choice B, 'complete,' is incorrect because complete proteins contain all essential amino acids in adequate amounts. Choice C, 'indispensable,' is incorrect as it refers to essential amino acids rather than the classification of plant proteins. Choice D, 'dispensable,' is also incorrect as it implies that these proteins are not necessary, which is not the case.

3. Which of the following is an example of a disaccharide?

Correct answer: D

Rationale: The correct answer is D, Maltose. A disaccharide is formed when two monosaccharides are joined together. Glucose, fructose, and galactose are all monosaccharides, not disaccharides. Therefore, they are not examples of disaccharides.

4. Where does the absorption of most nutrients occur?

Correct answer: B

Rationale: The absorption of most nutrients occurs in the small intestine. This is where digested food is broken down further and absorbed into the bloodstream through the intestinal walls. The large intestine primarily absorbs water and electrolytes, while the stomach mainly aids in digestion by breaking down food with gastric juices. The mouth is responsible for the initial mechanical breakdown of food through chewing and the enzymatic action of saliva, but absorption does not occur there.

5. The sum of all chemical processes inside living cells of the body that sustain life and health is known as:

Correct answer: C

Rationale: Metabolism is the correct answer as it refers to the sum of all chemical processes that occur within living cells to maintain life and health. Physiology (Choice A) is the study of how living organisms function but does not specifically refer to cellular chemical processes. Digestion (Choice B) is the process of breaking down food in the body, not the overall cellular processes. Nutrition (Choice D) is the process of obtaining and consuming food necessary for health and growth, but it does not encompass all cellular processes related to sustaining life and health.
