How is Breathing Related to Cellular Respiration? A Simple Guide

Breathing and cellular respiration are two vital processes that are essential for life. But how are they related? And what are the differences between them? In this article, we will explore these questions and learn more about the amazing ways our bodies use oxygen and carbon dioxide to produce energy.

What is Breathing?

Breathing is the process of taking in air and exhaling carbon dioxide. It involves the respiratory organs, such as the nose, mouth, pharynx, larynx, trachea, bronchi, bronchioles, and alveoli. Breathing is controlled by the brain and the nervous system, and it can be voluntary or involuntary. For example, when we sleep, we breathe involuntarily, but when we sing, speak, swim, or practice relaxation techniques, we breathe voluntarily.

The main purpose of breathing is to provide oxygen to the blood and to remove carbon dioxide from the blood. Oxygen is needed for cellular respiration, which is the process of breaking down glucose to produce energy. Carbon dioxide is a waste product of cellular respiration, which needs to be eliminated from the body.

What is Cellular Respiration?

Cellular respiration is the process of using oxygen and glucose to produce energy, water, and carbon dioxide. It occurs inside the cells, especially in the mitochondria, which are the powerhouses of the cell. Cellular respiration is controlled by enzymes, which are proteins that speed up chemical reactions.

The main purpose of cellular respiration is to produce energy in the form of ATP (adenosine triphosphate), which is used by the cells to perform various functions, such as growth, repair, movement, transport, synthesis, and signaling. Cellular respiration also produces water and carbon dioxide, which are released from the cells into the blood.

How are Breathing and Cellular Respiration Related?

Breathing and cellular respiration are related in that they both involve the use of oxygen and carbon dioxide to produce energy. However, they are different in that breathing is a physical process that occurs outside the cells, while cellular respiration is a chemical process that occurs inside the cells.

The relationship between breathing and cellular respiration can be summarized by the following equation:

\\begin {aligned} & {\\ce {C6H12O6}} + {\\ce {6 O2}} \\rightarrow {\\ce {6 CO2}} + {\\ce {6 H2O}} + {\\ce {ATP}} \\\\ &\\kern0.3em\\redE {\\text {glucose}}\\kern0.9em\\redE {\\text {oxygen}}\\kern1.0em\\redE {\\text {carbon}}\\kern1.1em\\redE {\\text {water}} \\kern1.1em\\redE {\\text {energy}} \\\\ [-0.30em] &\\kern8.3em\\redE {\\text {dioxide}} \\end {aligned} CX 6HX 12OX 6 + 6OX 2 → 6COX 2 + 6HX 2O + ATP glucose oxygen carbon water energy dioxide

This equation shows that glucose and oxygen are the inputs of cellular respiration, while carbon dioxide, water, and energy are the outputs. Breathing provides the oxygen needed for cellular respiration and removes the carbon dioxide produced by cellular respiration.

Why is Breathing and Cellular Respiration Important?

Breathing and cellular respiration are important because they enable us to live and grow. Without breathing, we would not be able to supply oxygen to our cells or get rid of carbon dioxide from our bodies. Without cellular respiration, we would not be able to produce energy from our food or use it for our daily activities.

Breathing and cellular respiration are also important because they help maintain homeostasis, which is the balance of internal conditions in our bodies. For example, breathing helps regulate the pH (acidity) of our blood by adjusting the amount of carbon dioxide we exhale. Cellular respiration helps regulate our body temperature by generating heat as a by-product of energy production.

Conclusion

Breathing and cellular respiration are two interrelated processes that allow us to use oxygen and carbon dioxide to produce energy. Breathing is a physical process that occurs outside the cells, while cellular respiration is a chemical process that occurs inside the cells. Both processes are essential for life and help maintain homeostasis in our bodies.

According to Boost Body Fit, breathing and cellular respiration are similar in that they both involve the use of oxygen and carbon dioxide to produce energy. However, according to Khan Academy, breathing and cellular respiration are different in that breathing is a process of taking in air and exhaling carbon dioxide, while cellular respiration is a process of using energy from organic molecules to produce organic molecules.
