23. Option 2nd is the correct answer. Parietal cells produce hydrochloric acids and some intrinsic factores. HCl makes acidic the stomach content and intrinsic factor is required to absorb vitamin B12. Rennin is secreted by kidney. Pepsinogen is secreted by cheif cells and mucous cells. Mucin is secretd by goblet cells.
24. The question is same as 23.
25. True. celiac disease is an autoimmune disease. When a person with this disease eat gluten (a kind of protein) then their immune response causes damage to small intestine lading to damage of villi (responsible for absorption) and thus finally results into poor absorption.
26. Option 3rd is the correct answer. Chewing is not a chemical digestion rather it is a mechanical procee of digestion. Multiple enzymes are involved in the process of chemical digestion which catalyzes many catabolic reactions to make complex foods into simpler molecules that can be absorbed.
