What type of reaction is the breakdown of glucose?
Overall Chemical Equation Since the breakdown of glucose is a chemical reaction, it can be described using the following chemical equation: C6H12O6 + 6 O2 –> 6 CO2 + 6 H2O, where 2870 kilojoules of energy are released for each mole of glucose that’s metabolized..
What does the breakdown of glucose produce?
Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy.
What is the first step in the breakdown of glucose?
Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. Glycolysis consists of an energy-requiring phase followed by an energy-releasing phase.
Why is the breakdown of glucose important?
Glucose is a carbohydrate, and is the most important simple sugar in human metabolism. … When oxidized in the body in the process called metabolism, glucose produces carbon dioxide, water, and some nitrogen compounds and in the process provides energy which can be used by the cells.
What is the second stage of glucose breakdown?
The second step of glycolysis involves the conversion of glucose-6-phosphate to fructose-6-phosphate (F6P). This reaction occurs with the help of the enzyme phosphoglucose isomerase (PI). As the name of the enzyme suggests, this reaction involves an isomerization reaction.
What are the four phases of glucose breakdown?
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.
What are the three ways of breakdown of glucose?
1) = In the presence of oxygen breaking down of glucose in pyruvate. 2) = Takes place in mitochondria of a cell. 3) = End products are carbon dioxide , water. 4) = More amounts of energy released.
What is the correct order of glucose catabolism?
Glucose catabolism occurs in a series of small, sequential, highly controlled and regulated steps (reactions). The processes involved are glycolysis, which is the first step of glucose breakdown, and it is followed by either fermentation or cellular respiration (depending on the availability of oxygen).
Where does the breakdown of glucose occur?
The initial breakdown of glucose occurs in the cell cytoplasm. This is an anaerobic reaction of cellular respiration, meaning that it does not require oxygen.
What is the last stage of glucose metabolism?
The stages that occur in the mitochondrion are known as cellular respiration. The last step (the electron transport system) require the presence of oxygen. The structure of mitochondria is important for them to work properly. The cristae provide extra surface area for the proteins (enzymes) of the ETS.
