The primary distinction between the digestive systems of cows and humans is that the former uses a foregut fermenter while the latter uses a straightforward monogastric digestion. The types of teeth, mouths, stomachs, guts, and digestive enzymes released by the gut also vary between the two digestive systems. Cows and humans have different digestive systems because they have evolved two different sorts of dietary patterns based on their capacities. The primary distinctions between the digestive systems of cows and humans are in the types of teeth, mouths, stomachs, and intestines, as well as the enzymes released.
Answer: The value of
for this reaction is 250000.
Explanation:
The given equation is as follows.

... (1)
... (2)
To balance the atoms, multiply equation (2) by 3. Hence, the equation (2) can be re-written as follows.
... (3)
Now, subtract equation (1) from equation (3). So, the equation formed will be as follows.

This equation can also be re-written as follows.

This equation is similar to the equilibrium equation given to us.
Therefore, during this subtraction the equation constants get divided as follows.
Thus, we can conclude that the value of
for this reaction is 250000.
