Question

Given below are two statements.
Statement I - Degradation of fats increases formation of ketone bodies in diabetes insipidus.
Statement II - Entero-gastrone slows gastric contractions and inhibits secretion of gastric juice.
In the light of above statements, select the correct option given below:

• A. Both statement I and statement II are correct.
• B. Both statement I and statement II are incorrect.
• C. Statement I is correct but statement II is incorrect.
• D. Statement I is incorrect but statement II is correct.

Hint:

Ketosis from fat breakdown is a feature of diabetes mellitus, not diabetes insipidus. Enterogastrone from the duodenum slows stomach activity.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept
Two separate facts are tested here: the cause of ketone body formation and the action of the hormone enterogastrone.

Step 2: Check Statement I
Ketone bodies rise when cells cannot use glucose and the body burns fats instead. This happens in diabetes mellitus (insulin deficiency).
Diabetes insipidus is caused by lack of ADH and only causes dilute urine and thirst, so Statement I is incorrect.

Step 3: Check Statement II
Enterogastrone is released by the duodenum when fatty chyme arrives. It slows gastric contractions and reduces gastric juice secretion, so Statement II is correct.

Step 4: Choose the option
Statement I is incorrect and Statement II is correct, which is option (D).

Final Answer:
Statement I is incorrect but Statement II is correct. \[ \boxed{\text{(D) }\text{Statement I is incorrect but statement II is correct.}} \]
