What is One Reason That Acetogenesis is Favored Over Methanogenesis

Question

What is one reason that acetogenesis is favored over methanogenesis in the termite gut?
A) The environment is anoxic.
B) Methanogens can use a wide range of substrates, but acetogens specialize in those produced in the termite gut.
C) Methanogens are not found in the termite gut.
D) Acetogens are better at colonizing the center of the gut, which is rich in H₂.

Accepted Answer

Acetogens are favored over methanogens in the termite gut because they are better at colonizing the center of the gut, which is rich in hydrogen (H₂). This adaptation allows them to efficiently utilize the available H₂ for acetogenesis, a process that converts carbon dioxide and hydrogen into acetate, which is a primary energy source for termites.
