Question

Which is the chemical equation for cellular respiration, and which statement describes the reaction?

Answer 1

The complete equation of cellular respiration is that 6 molecules of glucose reacts with 6 molecules of oxygen to give rise to 6 molecules of carbon dioxide and 6 molecules of water. ATP or energy is released out.  

Further Explanation:

Cellular respiration is known to be one of the most majestic and elegant metabolic pathways that takes place in living organisms. It comprises of three stages:

1. Glycolysis

2. Krebs cycle

3. Electron transport chain.  

During this, glucose molecules are slowly broken down into the water and carbon dioxide. Some ATP or adenosine triphosphate is generated directly in the reactions which convert the glucose molecule. Oxidative phosphorylation is basically powered by the movement of the electron via the electron transport chain which is a row of proteins pierced in the inner membrane of the mitochondria.  

1. The process intiates with the glycolysis. In this, the six carbon sugar called glucose undergoes a row of chemical reactions and in the end, gets transformed into the two molecule of pyruvate which is a three carbon molecule. During this, ATP is produced and NAD+ is converted into NADH.

2. The second phase is the pyruvate oxidation wherein each molecule of pyruvate goes into the matrix of mitochondria and gets converted into the two carbon molecule and then binds with the coenzyme A which is called acetyl CoA. During this, NADH is generated while carbon dioxide is released.  

3. The third phase is the Krebs cycle or citric acid cycle wherein the acetyl CoA combines with the four carbon molecule and undergoes a series of reactions, finally, generating four carbon starting molecule, NADH, ATP, and $\text{FADH}_{2}$. The last phase is the ETC or electron transport chain wherein NADH and $\text{FADH}_{2}$ deposit their electrons and gets back into their previous forms like NAD+ and FAD.

Answer 2

The right option is; glucose + oxygen = carbon dioxide + water-Energy is produced in the form of ATP.

Cellular respiration is the process whereby molecules are broken down by cells for energy. In this process, glucose (a complex sugar) is combined with oxygen to form water, carbon dioxide, and energy in the form of adenosine triphosphate (ATP).  

The chemical equation for cellular respiration is; C6H12O6 + 6O2 --> 6CO2 + 6H2O + 36 or 38 ATP . (1 glucose molecule + 6 oxygen molecules = 6 carbon dioxide molecules + 6 water molecules + 38 molecules of ATP).  where glucose and oxygen are the reactants, while water, carbon dioxide, and energy (ATP) are the products.
