Is glucose a reactant in the aerobic stages of cellular respiration? ›

During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. The overall equation for aerobic cellular respiration is: In cellular respiration, glucose and oxygen react to form ATP.

Aerobic respiration uses oxygen and is the primary form of energy production in human cells. Aerobic respiration uses oxygen and glucose as reactants and makes ATP, carbon dioxide and water as products.

Glucose is a 6-carbon structure with the chemical formula C6H12O6. It is a ubiquitous source of energy for every organism in the world and is essential to fuel both aerobic and anaerobic cellular respiration.

Glucose is essential in living organisms because it serves as the primary reactant used in cellular respiration, in which a series of pathways produces ATP, the main energy source for cells.

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

During cellular respiration, the reactants—glucose (sugar) and oxygen—combine together to form new products: carbon dioxide molecules and water molecules.

In aerobic respiration, oxygen is required to react with glucose to produce carbon dioxide, water, and energy in the form of ATP. In anaerobic respiration, glucose can be broken down into lactic acid to produce ATP.

The overall reaction is: C₆H₁₂O₆ + 6O₂ yields 6CO₂ + 6H₂O + energy (as ATP). Glucose (C₆H₁₂O₆ ) is oxidized to produce carbon dioxide (CO₂) and oxygen (O₂) is reduced to produce water (H₂O). This type of ATP production is seen in aerobes and facultative anaerobes.

Cellular respiration is a metabolic pathway that uses glucose to produce adenosine triphosphate (ATP), an organic compound the body can use for energy. One molecule of glucose can produce a net of 30-32 ATP.

Glucose + Oxygen → Carbon dioxide + Water + Energy

Aerobic respiration is a continuous process and it happens all the time inside the cells of animals and plants.

What are the reactants of aerobic cellular respiration? ›

Cellular respiration is the chemical reaction in which glucose and oxygen are turned into water, carbon dioxide, and energy (ATP). In this reaction, glucose and oxygen are reactants, while water, carbon dioxide, and energy (ATP) are products.

Changes in glucose concentration impact the rate of cellular respiration since all living cells require both glucose and oxygen to function correctly. A cell cannot create energy in the form of ATP molecules if its glucose level is low.

Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

The reactants for cellular respiration are glucose and oxygen. Glucose is a sugar molecule that is produced by plants through the process of photosynthesis. Plants use the sun's energy to form glucose from carbon dioxide and water, and energy is stored within the bonds of glucose.

Aerobic respiration is a series of enzyme-controlled reactions that release the energy stored up in carbohydrates and lipids during photosynthesis and make it available to living organisms. There are four stages: glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation.

The process begins with Glycolysis. In this first step, a molecule of glucose, which has six carbon atoms, is split into two three-carbon molecules. The three-carbon molecule is called pyruvate. Pyruvate is oxidized and converted into Acetyl CoA.
