The process by which body produces energy from glucose is called

Last Updated: 26 Jun 2026

This question examines a fundamental concept of human anatomy, physiology, health, nutrition, disease, or body regulation that frequently appears in SSC CGL General Science. A reliable solution begins by identifying the organ, tissue, cell, hormone, nutrient, pathogen, or biological process named in the stem and then linking it with its precise function or defining feature. The human body works through coordinated organ systems. Restate the question in your own words, predict the answer before checking the options, and confirm that the explanation and correct-option field both point to Cellular respiration.

DExcretion

Correct Answer: Cellular respirationYour Answer: B

Explanation

Therefore option B, Cellular respiration, is factually consistent with the stem, the marked correct index, and the explanation.✅ Correct Answer: B — Cellular respiration Cellular Respiration is the biochemical process by which cells convert glucose into energy (ATP). The equation is: Glucose (C6H12O6) + Oxygen (6O2) → Carbon dioxide (6CO2) + Water (6H2O) + Energy (ATP). Photosynthesis — Photosynthesis is the opposite process; it occurs in plants (chloroplasts) and uses sunlight + CO2 + water to produce glucose and oxygen. Humans cannot do photosynthesis. Digestion — Digestion breaks down food into smaller molecules (like glucose) in the digestive system; it is not the process of energy production from glucose. Excretion — Excretion is the elimination of metabolic waste products (urea, CO2, urine); not related to energy production. 📝 Important Note: Cellular Respiration = energy production from glucose. ATP = Adenosine Triphosphate = energy currency of cells. Mitochondria are the site of cellular respiration. 1 glucose molecule yields 36-38 ATP molecules.

Important Notes

Read the complete stem and identify the exact demand: organ, gland, hormone, cell, tissue, nutrient, enzyme, pathogen, vector, deficiency disease, body fluid, or physiological function.
Photosynthesis, Digestion, Excretion are eliminated here because none satisfies the precise requirement of the stem. Practising the reason for each rejection is more reliable than memorising only the correct choice.
Numerical biological facts often vary with age, sex, body size, and reference range. Use the standard approximate value expected in school-level competitive examinations and retain its unit.

FAQ

SSC CGL Human Body FAQs

Common questions and clear answers for this topic.

Which body systems are most important for SSC CGL preparation?

The digestive, circulatory, nervous, and skeletal systems appear most frequently, along with sensory organs and basic endocrine functions.

How many bones are there in the human body, and is this commonly asked?

Yes, the human body has 206 bones, and questions about the largest, smallest, and total bone count appear fairly often.

What kind of blood-related questions come up in SSC CGL?

Questions usually cover blood group compatibility, the role of platelets in clotting, and basic facts about blood pressure and heart function.

Do I need detailed biochemistry knowledge for the human body section?

No, most questions focus on what each organ does and why, rather than the detailed biochemical processes behind it.

How can I retain human body facts more effectively for the exam?

Linking facts to real-life observations, like why pulse is checked at the wrist, makes them easier to recall than memorizing textbook lines.
