Cows emit up to 200 L of methane (CH₄)through belching each day.The methane is produced by bacteria in their gut breaking down cellulose.The fact that cows belch methane and not carbon dioxide (CO₂)suggests which of the following is occurring?

Question

Quizplus · Accepted Answer

The fact that cows are producing methane suggests that anaerobic fermentation is occurring. This is because methane is a product of anaerobic fermentation, where bacteria break down organic matter without the presence of oxygen. In contrast, aerobic fermentation and respiration both produce carbon dioxide. Therefore, neither option A nor D is correct. Option B (anaerobic respiration) is also incorrect, as this process requires an electron acceptor other than oxygen, such as nitrate or sulfate, and does not produce methane as a byproduct.
