The question asks for the biological process that encompasses the use of food for energy, growth, and protection. We need to identify the term that broadly defines this entire scope of activities related to food utilization by an organism.
Correct Option: B) Nutrition is the process by which an organism obtains food and utilizes it for various life processes such as energy production, growth, and maintenance (protection and repair of tissues).
The question asks to identify the food component that does NOT provide energy to the body. This requires understanding the primary functions of different macronutrients and micronutrients.
Correct Option: C) Vitamins
Vitamins are organic compounds that are essential for normal metabolism, growth, and development. They act as coenzymes or cofactors in various biochemical reactions but do not provide direct energy (calories) to the body. Instead, they help the body utilize the energy from carbohydrates, fats, and proteins.
The question asks to identify the constituents of food from the given list. Food constituents are substances that provide nourishment essential for the maintenance of life and for growth. These include macronutrients and micronutrients, as well as water.
A) I, II, III and IV — All the listed items (proteins, carbohydrates, fats, vitamins, minerals, and water) are fundamental constituents of food necessary for human survival and well-being.
The question asks about the ideal percentage of carbohydrates in a balanced diet. A balanced diet provides all necessary nutrients in appropriate proportions to maintain health. Carbohydrates are a primary source of energy.
Correct Option: D) 60–70% is the ideal percentage of a balanced diet that should be contributed by carbohydrates. This range aligns with general nutritional guidelines that emphasize carbohydrates as the primary energy source for the body.
The question asks for the simplest unit of a carbohydrate. Carbohydrates are organic compounds that serve as a primary energy source for living organisms. They are classified based on the number of sugar units they contain. Understanding this classification is key to identifying the simplest unit.
Correct Option: A) Monosaccharide is the simplest unit of a carbohydrate because it is a single sugar molecule that cannot be hydrolyzed into smaller carbohydrate units.
The question asks to identify the primary storage form of carbohydrates in animals. This requires knowledge of common carbohydrate types and their biological roles in different organisms.
Correct Option: C) Glycogen is the main storage form of carbohydrates in animals. It is a highly branched polymer of glucose, primarily stored in the liver and muscle cells, providing a readily available source of energy.
