Question

Why is it important for the gut to have no O2?

a) Oxygen disrupts the digestive enzymes
b) Oxygen inhibits nutrient absorption
c) Anaerobic conditions aid in the growth of beneficial bacteria
d) Oxygen triggers allergic reactions in the gut

Answer 1

The gut having no O2 is important because it creates anaerobic conditions which aid in the growth of beneficial bacteria. Having no oxygen also prevents the growth of anaerobic pathogens that can cause infections.

Step-by-step explanation:

The gut having no O2 is important because it creates anaerobic conditions which aid in the growth of beneficial bacteria. Anaerobic bacteria, such as Bacteroidetes, play a crucial role in digestion and the production of valuable nutrients. Having no oxygen also prevents the growth of anaerobic pathogens that can cause infections.
