Which nutrient is the chief source of energy in the human diet?

Last Updated:

Built around the concept in “Which nutrient is the chief source of energy in the human diet?”, this bilingual General Science item checks whether a learner can connect a scientific term with its exact property, mechanism or function. The verified answer is Carbohydrates.

AProteins
BVitamins
CCarbohydrates
DMinerals
Correct Answer: CarbohydratesYour Answer: C

Explanation

Carbohydrates is the scientifically supported answer. Carbohydrates are the primary source of energy in the human diet. Biological questions are best solved by connecting a structure or nutrient with its physiological role, location and consequence of deficiency or malfunction. The alternatives Proteins, Vitamins and Minerals are legitimate scientific terms, but each belongs to a different function, property, material or context. If the topic involves the human body, check organ and function; in chemistry, check composition and reaction; in physics, check quantity and unit; and in environmental science, check layer and process.

Important Notes

  • Verified answer: Carbohydrates; option C, zero-based index
  • Core scientific fact: Carbohydrates are the primary source of energy in the human diet.
  • Distractors Proteins, Vitamins, Minerals represent different scientific associations.
  • Revision pair: “Which nutrient is the chief source of energy in the human diet? — Carbohydrates”.

What is General Science and which topics are important for competitive exams?

General Science covers basic concepts in Physics, Chemistry, Biology, and Earth Science. It is an important section in competitive exams like SSC CGL, UPSC Prelims, Railway NTPC, and Defence exams. Questions include scientific laws, inventions, human body systems, chemical reactions, and everyday science phenomena. NCERT Science books from Class 6 to 10 are recommended.

What are Newton's Laws of Motion?

Newton's Three Laws of Motion: 1) First Law (Law of Inertia) - An object remains at rest or in uniform motion unless acted upon by an external force. 2) Second Law - Force equals mass times acceleration (F=ma). 3) Third Law - For every action there is an equal and opposite reaction. These laws are fundamental to Physics and frequently asked in SSC CGL, Railway, and NDA exams.
