Carbon is released into the atmosphere by respiration from animals in the form of carbon dioxide, while photosynthesis from plants absorbs the carbon dioxide and gets it out of the atmosphere.
What are the reactants of photosynthesis?
The reactants of photosynthesis are carbon dioxide and water, meaning during photosynthesis carbon dioxide and water are taken in to create energy. The reactants of cellular respiration are glucose (sugar) and oxygen, these are taken in by animals and humans to produce energy. The cells found in both plants and animals need to produce energy.
What is the name of the sugar that is formed by the process of glycolysis?
C6H12O6 – While the formula can technically apply to a number of different molecules, depending on how the individual atoms within the molecule are connected, most of them are various types of sugars. The most famous formation of C6H12O6 is known as glucose, which can be known by other names including dextrose and even blood sugar. In the cells of animals, the process known as glycolysis converts glucose into pyruvate which generates two molecules of ATP along with it.

How much ATP does aerobic respiration produce?
The process of aerobic respiration produces a huge amount of ATP from each molecule of sugar. In fact, each molecule of sugar digested by a plant or animal cell yields 36 molecules of ATP! By comparison, fermentation usually only produces 2-4 molecules of ATP.
How does aerobic respiration work?
Instead of directly reducing intermediates of the Krebs cycle, aerobic respiration uses oxygen as the final electron receptor. But first, the electrons and protons bound to electron carriers (such as NADH), are processed through the electron transport chain. This chain of proteins within the mitochondrial membrane uses the energy from these electrons to pump protons to one side of the membrane. This creates an electromotive force, which is utilized by the protein complex ATP synthase phosphorylate a large number of ATD molecules, creating ATP.
Why is ATP not used for long term energy storage?
Because ATP is not stable over long periods of time, it is not used for long-term energy storage. Instead, sugars and fats are used as a long-term form of storage, and cells must constantly process those molecules to produce new ATP. This is the process of respiration. The process of aerobic respiration produces a huge amount ...
What is the process of converting sugars into energy?
Cellular respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.
Why is aerobic respiration so efficient?
Aerobic respiration is so efficient because oxygen is the most powerful electron acceptor found in nature. Oxygen “loves” electrons – and its love of electrons “pulls” them through the electron transport chain of the mitochondria.
Why is aerobic respiration important for eukaryotes?
Aerobic respiration is an extremely efficient process allows eukaryotes to have complicated life functions and active lifestyles. However, it also means that they require a constant supply of oxygen, or they will be unable to obtain energy to stay alive.
What is the main product of cellular respiration?
The main product of any cellular respiration is the molecule adenosine triphosphate (ATP). This molecule stores the energy released during respiration and allows the cell to transfer this energy to various parts of the cell. ATP is used by a number of cellular components as a source of energy.
