The enzyme that breaks down lipids in the small intestine is primarily produced by the: MCQ with Answer and Explanation

The enzyme that breaks down lipids in the small intestine is primarily produced by the:
A. Salivary glands
B. Pancreas
C. Liver
D. Stomach
Answer: Option B
Solution (By JKSSB Mock Tests)
Pancreatic lipase is the major enzyme for fat digestion, secreted by the exocrine pancreas into the duodenum. It hydrolyzes triglycerides into monoglycerides and free fatty acids, aided by bile salts that emulsify fats. Gastric lipase (stomach) plays a minor role. Liver produces bile but not lipase. Salivary glands produce salivary amylase.

Question #1
In the human body, the 'Cerebellum' is a large structure located at the base of the brain. Its primary functions include:
A. Processing visual and auditory information
B. Controlling emotions and memory
C. Coordinating voluntary movements, maintaining posture, and balance
D. Regulating heart rate and breathing

Correct Answer: Option C


Explanation:
The cerebellum, meaning 'little brain', is a highly folded structure located at the posterior base of the skull, beneath the occipital lobes of the cerebrum and behind the brainstem. While it does not initiate movement, its primary functions are to coordinate voluntary motor movements, ensure muscle synergy, maintain posture, and regulate balance and equilibrium. It receives sensory input from the spinal cord, vestibular system, and cerebral cortex, and fine-tunes motor output to ensure smooth, accurate movements. Damage to the cerebellum results in ataxia (clumsy, uncoordinated movements).

Question #3
National parks and wildlife sanctuaries are examples of which type of conservation?
A. Cryopreservation
B. Tissue culture
C. Ex-situ conservation
D. In-situ conservation

Correct Answer: Option D


Explanation:
In-situ (on-site) conservation involves the conservation of species in their natural habitats. National parks, wildlife sanctuaries, and biosphere reserves are examples of in-situ conservation. Ex-situ (off-site) conservation involves taking endangered species out of their natural habitat and placing them in special settings like zoological parks, botanical gardens, and seed banks for conservation and breeding.
