Question

\[{C_6}{H_{12}}{O_6} + {\text{ }}6{O_2} \to \]
A.\[C{O_2}\]
B.\[{H_2}O\]
C.Heat
D.All of the above

Answer 1

Hint: We can understand that the above reaction is the reaction between the glucose and the oxygen which is the energy release reaction. When we react to glucose with molecular oxygen, we get carbon dioxide and water. And we must understand that the carbon atoms in glucose are oxidized.

Complete step by step answer:
Let’s start with discussing the reactants given to us, we are provided with \[{C_6}{H_{12}}{O_6}\] which is the chemical formula of glucose. Glucose the monosaccharide and provide us energy to do our work. The other reactant given to us is oxygen. So the reaction they are talking about is the reaction of energy production by our body. When we eat food the starch and other carbohydrates are broken into the glucose, which when comes into contact with oxygen produces the energy along other compounds. The oxygen is made available by respiration.
The reaction is as follows:
${C_6}{H_{12}}{O_6} + {\text{ }}{O_2} \to C{O_2} + {\text{ }}{H_2}O{\text{ }} + {\text{ }}Heat$
Now balancing this equation we get
${C_6}{H_{12}}{O_6} + {\text{ }}6{O_2} \to 6C{O_2} + {\text{ }}6{H_2}O{\text{ }} + {\text{ }}Heat$
So, from this we can conclude the products that we achieve after this reaction is which we exhale during respiration, \[{H_2}O\] which is used by the body as body, require to maintain water balance, and the Heat is the form of energy which our body utilizes to perform different functions. Different body parts require different amounts of energy to work, even when you are sleeping the energy is being used to perform different activities like breathing and keeping your brain active.
So, the correct answer to this question is option, D.

Note:
The reaction between the glucose and oxygen is not as simple as it looks. The products that are shown are only the end product, the process it follows is much more complex and hence it shows the complexity of life. The energy that we get is in the form of \[NADH\] (nicotinamide adenine dinucleotide) which is used by our body to perform various tasks. Also if excess glucose is present in the body, it gets stored in the form of Glycogen.
