What Are the Key Differences Between Breathing and Respiration, with Diagram and Easy Examples?
Understanding the difference between breathing and respiration is fundamental in biology, especially for students preparing for exams like CBSE, ICSE, or NEET. Though both processes are vital for survival, they are not the same. This page explores definitions, processes, and key distinctions, making it easy to grasp these life processes and apply them in real-life scenarios and academics.
Breathing and Respiration: Definition and Explanation
Breathing is the mechanical, physical act during which living organisms take in oxygen-rich air and release carbon dioxide. It happens in the respiratory organs, such as the lungs in humans. Respiration, on the other hand, is a biochemical process at the cellular level, where glucose breaks down (using oxygen or without it) to release energy or ATP, along with waste like carbon dioxide and water.
- Breathing (Ventilation): Physical act of inhaling and exhaling air for gas exchange.
- Respiration: Chemical process within cells that releases energy by breaking down glucose, supporting all bodily functions.
Students often mix these terms, but in biology, each refers to a unique set of steps with different outcomes and roles in life support.
Process of Breathing: Steps Explained
- Air enters the nose or mouth during inhalation.
- It passes through the trachea and bronchi into the lungs.
- Within the lungs, it reaches the alveoli for gas exchange.
- Oxygen diffuses into the blood; carbon dioxide from the blood enters the alveoli.
- Carbon dioxide is exhaled when the diaphragm and chest muscles relax.
The entire process is coordinated by the diaphragm, intercostal muscles, and the respiratory tract structures. For a more detailed diagram of alveoli and their significance in breathing, see alveoli.
Process of Respiration: Cellular Level
- Glucose from food reaches cells via the bloodstream.
- Oxygen, delivered by red blood cells, enters body tissues.
- In mitochondria, glucose reacts with oxygen (aerobic respiration).
- ATP (energy) is produced, fueling activities like movement, growth, and repair.
- Waste products—carbon dioxide and water—are formed and transported out of the cell.
A similar breakdown occurs in plants, with gas exchange being managed by stomata. Respiration can also occur without oxygen (anaerobic), as seen in muscles during intense activity or in yeast cells. If you want to explore the specifics of mitochondria, visit mitochondria on Vedantu.
Tabular Comparison: Difference Between Breathing and Respiration
| Basis | Breathing | Respiration |
|---|---|---|
| Process Type | Physical, mechanical | Biochemical, metabolic |
| Occurs in | Lungs and air passages | All living cells (mainly mitochondria) |
| Energy Production | No ATP produced | ATP produced (energy release) |
| Control | Voluntary and involuntary | Always involuntary |
| Enzymes Needed | No | Yes |
| Interaction | Gas exchange with environment | Gas exchange within cell |
| End Products | Exchange of O2 and CO2 | ATP, CO2, H2O |
This table summarizes the difference between breathing and respiration definition, processes, and where they take place. For exam purposes, this classification is especially important for students in Class 9 and 12.
Types of Respiration: Aerobic and Anaerobic
| Feature | Aerobic Respiration | Anaerobic Respiration |
|---|---|---|
| Oxygen Requirement | Yes | No |
| Site in Cell | Mitochondria | Cytoplasm |
| ATP Produced (per glucose) | 36–38 | 2 |
| End Products | CO2 and H2O | Lactic acid (in muscles) or alcohol + CO2 (in yeast) |
Knowing these types helps in answering difference between breathing and respiration MCQs, especially those that focus on energy production. More about energy release can be connected to food science topics in food science.
Difference Between Breathing and Respiration: Real-life Examples
- Holding your breath during swimming affects only breathing; your cells continue cellular respiration until oxygen is depleted.
- Yeast producing bubbles in bread dough demonstrates anaerobic respiration, not breathing.
- During intense exercise, muscle cells switch to anaerobic respiration, causing fatigue and lactic acid buildup.
- Plants "breathe" through stomata but respire in every living cell, day and night.
These difference between breathing and respiration examples provide clarity and application for both biology classes and entrance exams. For more examples of plant adaptations and plant respiration, visit Respiration in Plants.
Why the Difference Between Breathing and Respiration Matters
Mixing up these terms can lead to confusion in exams and in real-world applications, like medical emergencies. Accurate understanding helps in fields like life science, medicine, and environmental studies, linking core biological processes to health and ecological balance.
Breathing and Respiration: Key Points for Students (Class 12 & NEET)
- Breathing is a physical process; respiration is a chemical process within cells.
- Only respiration produces ATP, the energy currency for all biological functions.
- Breathing can be partially controlled (voluntary); cellular respiration is always automatic (involuntary).
- Oxygen is vital for life because of its role in cellular respiration, not just for breathing.
- Both are essential, but only respiration keeps cells—and you—alive on a molecular level.

FAQs on Difference Between Breathing And Respiration Explained for Students
1. What is the difference between breathing and respiration?
Breathing is the physical process of taking in oxygen and expelling carbon dioxide, while respiration is a biochemical process where cells use oxygen to produce energy from food.
Key differences:
- Breathing is a mechanical process; respiration is a chemical process.
- Breathing involves inhaling and exhaling gases; respiration involves energy release in cells.
- Breathing occurs in lungs (external); respiration occurs at cellular level (internal).
2. Why is breathing necessary for respiration?
Breathing is necessary for respiration because it supplies the oxygen needed by cells and removes carbon dioxide, a waste product of cellular respiration.
- Inhalation brings in oxygen required for cellular energy production.
- Exhalation expels carbon dioxide produced by cells.
3. What are the two main types of respiration?
Respiration can be classified as:
- Aerobic respiration (requires oxygen): Produces more energy.
- Anaerobic respiration (does not require oxygen): Produces less energy and occurs in some cells or conditions.
4. How does gaseous exchange take place in humans?
Gaseous exchange happens in the alveoli of the lungs, where oxygen diffuses into the blood and carbon dioxide exits the blood to be breathed out.
- Oxygen from inhaled air passes into blood capillaries.
- Carbon dioxide from blood is expelled during exhalation.
5. What are the steps involved in breathing?
Breathing involves two main steps:
- Inhalation: Taking air rich in oxygen into the lungs.
- Exhalation: Removing air rich in carbon dioxide from the lungs.
