How does cellular respiration work?
cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
Is cellular respiration anabolic?
Photosynthesis, which builds sugars out of smaller molecules, is a "building up," or anabolic, pathway. In contrast, cellular respiration breaks sugar down into smaller molecules and is a "breaking down," or catabolic, pathway.
Why can cellular respiration be considered a form of combustion?
Cellular respiration resembles ordinary combustion or burning in the breakdown of chemical bonds, use of oxygen, production of carbon dioxide, and release of energy, but there are some fundamental differences between the two processes.
Is cellular respiration Endergonic or exergonic?
exergonicCellular respiration is an exergonic (energy-releasing) process.
How does cellular respiration work?
Cellular respiration involves breaking the chemical bonds holding glucose together, which released the chemical energy of those bonds. That energy is converted into heat energy and ATP (adenosine triphosphate), an essential compound for cell survival.
What is the chemical reaction in cellular respiration?
Chemical reactions, like those involved in cellular respiration, involve changing matter from one form to another. This rearrangement of matter can be described using a chemical equation. The chemical equation for cellular respiration looks like this:
How does carbon dioxide get processed?
Some of these things get processed through a chemical reaction called cellular respiration. This is where glucose (a sugar present in the food we eat) and oxygen (from the air we breathe) get combined to form carbon dioxide and water. The water is used by the body, while the carbon dioxide is expelled through our lungs.
What is the cell's way of transferring energy between different places inside the cell?
In a nutshell, ATP is the cell's way of transferring energy between different places inside the cell; it is used by the cells to keep them operating. During cellular respiration, chemical energy - energy stored in the bonds holding molecules together - is changed into ATP and heat energy inside each of our cells.
What is the most important process in the human body?

What are the two types of respiration?
Those are physiological respiration (breathing) and cellular respiration. The physiological respiration is defined as the movement of oxygen (O 2) molecules from outside environment to the cells in the inner tissues of the body and the movement of carbon dioxide (CO 2) out of the body in the opposite direction. The other phase of the respiration could be defined as a biochemical reaction which is known as cellular respiration. Cellular respiration is of two types; aerobic and anaerobic. The glucose breaks into carbon dioxide and water by using atmospheric oxygen that is gained in the physiological respiration by cells in the tissues. The energy is produced by cellular respiration , and this energy is stored in ATP molecules. The oxygen is present in this type of cellular respiration, so it is also called as aerobic cellular respiration. This energy is extremely important for catabolic (breaking reactions) and anabolic (synthesizing reactions) pathways in the metabolism. In bacteria, the cellular respiration is little bit different and takes place without oxygen. It is called as anaerobic cellular respiration. In anaerobic process, alcohol and carbon dioxide are produced instead of water. In human also the anaerobic type of cellular respiration is possible in the absence of oxygen. Two molecules of lactic acids are produced from a glucose molecule in humans’ anaerobic respiration. Aerobic cellular respiration produces more energy (38ATP) than anaerobic cellular respiration (2ATP). The key difference between respiration and cellular respiration is, respiration is the entire process which consists of two phases (physiological respiration and cellular respiration) whereas, cellular respiration is only one phase of the respiration process where glucose is converted to energy in the presence of oxygen in cellular level.
