Question 1
How many calories are in one gram of fat?
Correct Answer:
9 kcal
Explanation:
Fats store the most energy per gram among the main nutrients. Their chemical structure holds a lot of energy in the carbon–hydrogen bonds, and fat contains relatively little oxygen, so when it’s metabolized a large amount of energy is released. The standard energy yield used in nutrition is about 9 kilocalories per gram for fat. In comparison, carbohydrates and proteins provide roughly 4 kcal per gram, and alcohol about 7 kcal per gram. So the correct value is 9 kcal per gram.
Question 2
What is the hot holding temperature for cooked foods?
Correct Answer:
63°C
Explanation:
Hot holding means keeping cooked foods hot during service to prevent bacteria from multiplying. Bacteria grow rapidly in the danger zone, roughly 5°C to 63°C, so the safe minimum hot holding temperature is 63°C. Keeping foods at 63°C or higher prevents growth and reduces toxin risk. The other options are below that minimum (60°C and 50°C), which would allow bacteria to multiply, while 70°C is also safe but not the minimum the question targets, so 63°C is the best answer.
Question 3
Which diet is defined by no pork or beef and notes that some Hindus are vegetarians?
Correct Answer:
Hindus diet
Explanation:
Dietary choices often reflect beliefs about sacred animals and acceptable foods. In Hinduism, cows are revered, so beef is commonly avoided, and many followers also choose vegetarian meals. This combination—no beef and often no meat at all—fits the Hindu diet description best. The other diets are defined by different rules: Muslims avoid pork entirely (beef can be eaten if halal), Jewish dietary laws forbid pork and require kosher preparation for beef, and a pescatarian diet centers on including fish while excluding other meats, but isn’t defined by Hindu beliefs.
Question 4
What term describes fatty acids with one or more double bonds between carbon atoms and are not fully saturated with hydrogen?
Correct Answer:
Unsaturated fatty acids
Explanation:
Think of how fatty acids are built from carbon chains with hydrogen atoms attached. If there are no double bonds, the chain is fully saturated with hydrogen. When there is one or more double bonds between carbon atoms, the chain cannot hold all possible hydrogens, so it is not fully saturated. That situation describes unsaturated fatty acids. Within unsaturated fats, one double bond means monounsaturated, while more than one double bond means polyunsaturated. Trans fatty acids are a subset of unsaturated fats where the hydrogen arrangement around the double bond is trans, but the key idea for this item is the presence of one or more double bonds, not full hydrogen saturation.
Question 5
Which of the following is listed as a function of fat?
Correct Answer:
Thermal insulation
Explanation:
Fat serves as an insulating layer under the skin, trapping air and slowing heat loss from the body. This helps keep body temperature stable in cooler conditions. While fat is a major energy store, it isn’t the only energy source—carbohydrates and proteins also provide energy, so it isn’t correct to say it’s the only source. We don’t aim for zero body fat; some fat is necessary for health, cushioning, and hormonal balance. And far from inhibiting vitamin absorption, fat actually aids the absorption of fat-soluble vitamins A, D, E, and K.
