Question

Which reaction takes place during respiration?
$A) 6C{O_2} + 6{H_2}O \to 6{O_2} + {C_6}{H_{12}}{O_6} \\\ B) C + {O_2} \to C{O_2} \\\ C) C + \dfrac{1}{2}{O_2} \to CO \\\ D) {C_6}{H_{12}}{O_6} + 6{O_2} \to 6C{O_2} + 6{H_2}O \\\$

Answer 1

Solution

Respiration is one of the biological processes that is necessary to occur for life to continue. It involves inhaling and exhaling. It is a common process carried out by all the living creatures.

Complete answer:
One may be aware of how all the mammals respire but even the plants respire, respiration in plants is carried out on the surface of their leaves through small openings that are not visible to the naked eye called stomata.
We are aware of the fact that we humans exhale carbon dioxide that the plants intake to give us oxygen that we further inhale. If it was not for the supply of oxygen human life cannot continue. Let us understand this process in detail, respiration is of two types aerobic and anaerobic. Aerobic respiration is carried out in oxygen releasing a lot of energy whereas anaerobic respiration is carried under absence of oxygen.
Carbohydrates are well known organic constituents of plants (exist as starch, cellulose and sugars ). They are synthesized by plants during photosynthesis. It acts as a major chemical repository for solar energy. Their energy is released when animals or plants metabolize carbohydrates to carbon dioxide and water which occurs like
${C_6}{H_{12}}{O_6} + 6{O_2} \to 6C{O_2} + 6{H_2}O$ (glucose is further classification of carbohydrates)
The metabolism of carbohydrates also takes place through a series of enzyme catalyzed reactions in which the energy yielding step is an oxidation. The synthesis of ATP from ADP and hydrogen phosphate ions. This reaction takes place in all living organisms.

Hence we can conclude that the correct option is D.

Note: Carbohydrates that cannot be hydrolysed are monosaccharides on molecular basis, though it undergoes hydrolysis to produce two molecules and is called disaccharide. Glucose is a type of monosaccharide.
