One (1) kilocalorie is equivalent to how many calories?
100,000 calories
100 calories
10,000 calories
1,000 calories
The Correct Answer is D
A. 100,000 calories is much larger than a kilocalorie and does not correspond to the standard energy conversion used in nutrition.
B. 100 calories is equivalent to 0.1 kilocalorie, so this is too small to define a kilocalorie.
C. 10,000 calories is also much greater than the actual equivalent of one kilocalorie.
D. One kilocalorie (kcal) is equal to 1,000 calories (cal). In nutrition, the term “calorie” commonly refers to a kilocalorie, which is the amount of energy required to raise the temperature of 1 kilogram of water by 1°C. Food labels use kilocalories to quantify the energy content of foods, which helps guide dietary intake and energy balance.

Correct Answer is A
Explanation
A. Aerobic exercise involves continuous, rhythmic movements of large muscle groups, such as those in the legs and arms, that increase the body’s demand for oxygen. This type of exercise improves cardiovascular and respiratory efficiency, increases endurance, and helps with weight management. Examples include running, swimming, cycling, and brisk walking. During aerobic exercise, the heart rate and breathing rate increase to supply sufficient oxygen to working muscles.
B. Lengthening muscles using slow, controlled movements describes stretching exercises, which improve flexibility but do not primarily enhance cardiovascular endurance or oxygen utilization.
C. Physical activity not related to a person’s occupation is simply recreational or leisure activity. While some recreational activities can be aerobic, this description does not define aerobic exercise itself.
D. Exercise in which muscles work against resistance describes anaerobic or resistance training, such as weightlifting or strength training. While these activities build muscular strength and power, they do not primarily rely on oxygen for energy production.
