“Cellular Respiration” Possible
These 2 words “respiration” and “cellular respiration” mean two different things:
Respiration is “the act of breathing” by the lungs.
Cellular respiration is “the act of releasing energy” by cells’ mitochondria.
Although they mean different things, they do affect each other because Respiration makes Cellular respiration possible–See below.
From this comic, you can see that respiration helps ensure a steady supply of oxygen for the cellular respiration to use, and it even helps get rid of carbon dioxide afterwards!
This is why you have to keep breathing (engage in respiration) to survive because without oxygen in your body, cellular respiration would stop and cause your whole body to shut down due to lack of energy! So, don’t hold your breath for too long, be sure to keep breathing!
Next Generation Science Standards:
MS-LS1-3. Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.
MS-LS1-7. Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.
HS-LS1-2. Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
HS-LS1-3. Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.
HS-LS1-6. Construct and revise an explanation based on evidence for how carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form amino acids and/or other large carbon-based molecules.
HS-LS1-7. Use a model to illustrate that cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed resulting in a net transfer of energy.
HS-LS2-3. Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.
HS-LS2-5. Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.

These are a special type of organelles responsible for using glucose to release energy for the cell. For more information, see this comic post (will open a new tab): Mitochondria Definition
Lungs are a pair of organs that engaging in respiration (typically called “breathing”). You can find more information on the importance of lungs in this post on the lungs’ importance: http://owlcomics.com/index.php/2017/05/11/lungs/. If you want to know what the lungs are made of, view this post: http://owlcomics.com/index.php/2017/05/06/alveoli/
Cellular respiration is the process that supplies the cells (as well as a large organism like a human) with the energy necessary for survival. We eat food and breathe air for the very purpose of gathering the necessary materials to keep cellular respiration going nonstop. The process of cellular respiration is carried out by cells’ mitochondria.
They are the “ingredients” of a chemical reaction. In a chemical reaction, reactants are used to produce “products”, which are the end results of a reaction.
Glucose is the simplest form of sugar and contains a lot of energy–think of the phrase “sugar-rush”. Because it is “simple”, it can be easily absorbed into an organism’s body/cells to provide the organism with energy.
Nucleus is the most important organelle in a cell and it stores the genetic material. You can find more information on the nucleus here.
This word is short for “deoxyribonucleic acid”, and it is the molecule that makes up organisms’ genetic materials. Its slight variant “RNA” (ribonucleic acid) is sometimes used as genetic materials for more primitive/simple organisms.
