Q57. Consider the following statements regarding dietary carbohydrates:
I. Monosaccharides are the simplest form of carbohydrates.
II. Glycogen is the storage form of carbohydrates in plants.
III. Cellulose cannot be digested by the human digestive system.
Which of the above statement(s) is/are correct?
I. Monosaccharides are the simplest form of carbohydrates.
II. Glycogen is the storage form of carbohydrates in plants.
III. Cellulose cannot be digested by the human digestive system.
Which of the above statement(s) is/are correct?
Explanation
Monosaccharides like glucose are the simplest carbohydrates and serve as the basic building blocks for more complex types. Cellulose is a structural carbohydrate in plants that the human digestive system cannot break down, although it provides essential dietary fiber. Glycogen is the storage form of carbohydrates in animals, not plants; plants store their excess carbohydrates in the form of starch.
Q58. Which vitamin is NOT part of the Vitamin B complex?
Explanation
Riboflavin, thiamine and folic acid belong to the Vitamin B complex. Tocopherol is vitamin E, so it is not part of the B complex.
Q59. The condition where the bones of children become soft and bent due to Vitamin D deficiency is known as:
Explanation
Rickets is a childhood condition characterized by the softening and weakening of bones, often leading to skeletal deformities like bowed legs. It is primarily caused by a prolonged deficiency of Vitamin D, which is essential for the absorption of calcium and phosphorus. Without these minerals, the growing bone tissue cannot mineralize properly, resulting in structural weakness and an increased risk of fractures.
Q60. Which macronutrient has the highest energy density, providing approximately 9 kilocalories per gram?
Explanation
Among the primary macronutrients, fat has the highest energy density, providing approximately nine kilocalories per gram. In contrast, both proteins and carbohydrates provide about four kilocalories per gram. Because of this high energy concentration, the body utilizes fats as an efficient way to store energy over long periods, while also providing essential fatty acids necessary for various biological functions.Answer key for these questions
