Question

Consider the following statements. Statement I: Main region of digestion in stomach in man is pyloric part. Statement II: Lipase of bile juice plays an important role in digestion of fats.

• A. Both statement I and statement II are true
• B. Both statement I and statement II are false
• C. Statement I is true, but statement II is false
• D. Statement I is false, but statement II is true

Hint:

Remember: \[ \boxed{ \begin{aligned} &\text{Main digestion} &&\rightarrow \text{Small intestine} &\text{Bile juice} &&\rightarrow \text{No enzymes; emulsifies fats} \end{aligned} } \]

Answer 1

The Correct Option is B

Step 1: Evaluate Statement I. The main region of digestion in humans is the \[ \boxed{\text{Small intestine (especially duodenum), not the pyloric part of the stomach}.} \] Hence, \[ \boxed{\text{Statement I is false}.} \]

Step 2: Evaluate Statement II. Bile juice contains \[ \boxed{\text{no digestive enzymes}.} \] It contains bile salts that emulsify fats, whereas fat digestion is carried out mainly by pancreatic lipase. Hence, \[ \boxed{\text{Statement II is false}.} \]

Step 3: Choose the correct option. Since both statements are false, \[ \boxed{(B)} \] is the correct answer.
