what is the chemical equation for digestion
Answers
Answer:
Digestion in our body is also an example of decomposition reactions. The starch decomposes in to sugar in the body and proteins get decomposed into smaller substances called amino acids. Another example of a combination reaction is when the walls are white washed with lime.
Explanation:
Biologically, methane is produced by methanogens, which are Archeabacteria. They do not utilize carbohydrates such as cellulose or glucose directly. Instead, they typically consume acetate or a mixture of hydrogen gas and carbon dioxide. These stoichiometry of these two processes is
4H2+CO2⟶CH4+2H2O or
CH3C(O)OH⟶CH4+CO2.
To get overall conversion of cellulose to methane, the cellulose is first fermented by the enteric bacteria you read about, which can produce acetate, hydrogen and carbon dioxide by a variety of pathways. These products are then utilized by the methanogens. One example of an enteric fermentation would be
C6H10O5+3H2O⟶2CH3C(O)OH+4H2+2CO2.
Combining this with the methanogenesis reactions, we can write the net equation of
C6H10O5+H2O⟶3CH4+3CO2
