Question

Give examples to prove that microbes release gases during metabolism.

Answer 1

The examples of micro organism that release gases for the duration of metabolism are:

(a) Microorganism and fungi carry out the technique of fermentation and throughout this process, they launch carbon dioxide. Fermentation is the system of converting a complex organic substance right into a less complicated substance with the motion of bacteria or yeast. Fermentation of sugar produces alcohol with the release of carbon dioxide and very little energy.

Glucose → ALCOHOL+ ENERGY+CO2

(without oxygen)

b)The dough used for making idli and dosa gives a puffed appearance. this is because of the motion of micro organism which releases carbon dioxide. This CO2 launched from the dough gets trapped within the dough, thereby giving it a puffed appearance.
