Cellular respiration is the process by which biological fuels are oxidized in the presence of an inorganic electron acceptor, such as oxygen, to drive the bulk production of adenosine triphosphate (ATP), which contains energy.
- C₆H₁₂O₆ (s) + 6 O₂ (g) → 6 CO₂ (g) + 6 H₂O (l) + energy
Learn how glucose is broken down into carbon dioxide and water in four stages of cellular respiration: glycolysis, pyruvate oxidation, citric acid cycle, and oxidative phosphorylation. See diagrams, examples, and questions to test your understanding of this metabolic pathway.
- if glycolysis requires ATP to start how did the first glycolysis in history happen?You must remeber that life on this planet has been evolving for billions of years, it is highly unlikely that the originating system resembles the...
- What is the role of NAD+ in cellular respiration. Why is the role NAD+ plays so important in our abi...Hello Breanna! NAD+ is an electron transport molecule inside the cristae of a cell's mitochondria. In glycolysis, the beginning process of all type...
- When it states in "4. Oxidative phosphorylation" that the NADH and the FADH2 return to their "empty"...the empty state of FADH2 is FADH, after oxidation it loses 1 h+ ion and elctron.
- I have a question... Which part of the body will most likely use the cellular respiration? Is it lun...Cellular Respiration happens in your cells and you entire body is made up of cells, it goes on all throughout your body including your lungs and br...
- When the electron carriers NAD+ and FAD gain electrons, why are 2 hydrogen ions also being added?The free energy from the electron transfer causes 4 protons to move into the mitochondrial matrix. In other words, electrons provide energy for hyd...
- Does the glycolysis require energy to run the reaction?Yes glycolysis requires energy to run the reaction. 2 ATPs are used up by glycolysis this then begins the oxidative process of glycolysis.
- Aren't internal and cellular respiration the same thing?Cellular respiration is oxidative metabolism of glucose which takes place in mitochondria and in the cell. Internal repsiration is gas exchange bet...
- In the Citric Acid Cycle (Krebs Cycle), would the four-carbon molecule that combines with Acetyl CoA...Yes. Acetyl CoA and Oxaloacetic Acid combine to form a six-carbon molecule called Citric Acid (Citrate).
- I was taught that it was Glycolysis, Pyruvate Oxidation, Krebs cycle, Electron Transport, and then C...It is the latter...the same thing is being said in different terms. - Glycolysis and pyruvate oxidation are directly mentioned. - Citric Acid cycle...
- After oxidative phosphorylation, the ATP created is in the mitochondrial matrix, right? If so, how d...Just like the cell membrane, the mitochondrion membranes have transport proteins imbedded in them that bring in and push out materials.
Jan 15, 2021 · Learn how cells convert sugars into energy through aerobic and anaerobic respiration. Find out the products, purpose and types of cellular respiration, and the difference between glycolysis, reduction and Krebs cycle.

Learn about the process of cellular respiration, how it releases energy and involves glucose, oxygen, carbon dioxide and water. Read the article and answer the questions aligned to NGSS standards.
- I don’t understand how both animal and _plant cells_ release carbon dioxide during cellular respirat...Photosynthesis uses energy (from the sun) to convert water and carbon dioxide into glucose and oxygen. Then the glucose can be stored for later use...
- isn't respiration basically breathing?Technically speaking, breathing is the process of ventilating air in and out of your body, while respiration is the mitochondrial task of using the...
- How does your body turn glucose and oxygen into carbon dioxide and waterChemistry. A chemical reaction occurs inside your mitochondria that results in the rearranging of the atoms in the inputs.
- what does glucose meanits a simple sugar and its your body's main source of energy
- what are inputs of cellular respiration?what comes in
- What is mitochondriamitochondria are the organelles that convert sugars and oxygen into carbon dioxide, water, and energy.
Cellular respiration is the process by which individual cells break down food molecules, such as glucose and release energy. The process is similar to burning, although it doesn’t produce light or intense heat as a campfire does.
Learn how cells extract energy from fuel molecules through cellular respiration, a series of metabolic pathways. Explore the steps, variations, and regulation of this process with videos, articles, and exercises.
