Sucrose: glucose + fructose sucrose is a disaccharide made from glucose and fructose
glucose: C(sub 6)H(sub 12)O(sub6)fructose: C(sub 6)H(sub 12)O(sub6)sucrose: C(sub 12)H(sub 22)O(sub 11)a water molecule, H(sub 2)O gets removed which is why there are 2 less hydrogens and one less oxygen
I think the correct answer from the choices listed above is the second option. The enzyme pepsin that is present in the stomach denature in the intestine due to the alkaline environment of the intestine. This is because pepsin has an optimum pH that is very low which is ideal for the acidic conditions of the stomach.
