Biology Question on Microbes in human welfare
Ruminant animals can digest cellulose in their food, where as human beings are unable to do so. This is because
A
Cellulose reduces the bulk of food
B
Methanogens are absent in human gut
C
Methanogens re present in human gut
D
Cellulose is a complex sugar b
Answer
Methanogens are absent in human gut
Explanation
Solution
Methanogens are bacteria that produce methane during the breaking down of substrates like cellulose. Plants are the major food consumed by ruminant animals. Cellulose is a polymer of glucose found in the cell wall of plants. The gut of the ruminant animals have methanogens that help in the digestion of cellulose and produce methane. Methanogens are absent in the case of human beings. Because of this reason, humans are unable to digest cellulose.
