Which of the following scientists is credited with the discovery of the 'Krebs cycle' (Citric Acid Cycle)?
A. Otto Warburg
B. Hans Adolf Krebs
C. Arthur Kornberg
D. Melvin Calvin
Answer: Option B
Solution (By JKExamLibrary)
The Krebs cycle, also known as the citric acid cycle or TCA cycle, is the central metabolic pathway for the oxidation of acetyl-CoA to produce energy (ATP, NADH, FADH2). It was discovered by the British-German biochemist Sir Hans Adolf Krebs in 1937. He was awarded the Nobel Prize in Physiology or Medicine in 1953 for this discovery. Melvin Calvin elucidated the carbon pathway in photosynthesis.

Question #2
In the human body, the 'Corpus callosum' is a large band of nerve fibers that connects the:
A. Left and right cerebral hemispheres
B. Brain and spinal cord
C. Thalamus and hypothalamus
D. Cerebrum and cerebellum

Correct Answer: Option A


Explanation:
The corpus callosum is the largest white matter structure in the brain, consisting of over 200 million axons. It forms a broad, flat band located deep in the longitudinal fissure (the cleft between the two hemispheres). Its primary function is to serve as the main communication pathway, allowing the left and right cerebral hemispheres to share information, coordinate activities, and integrate sensory, motor, and cognitive functions.

Question #3
The voice box or sound-producing organ in humans is the:
A. Pharynx
B. Larynx
C. Trachea
D. Bronchi

Correct Answer: Option B


Explanation:
The larynx, also called the voice box, contains vocal cords that vibrate as air passes, producing sound. It is located at the top of the trachea. The trachea (windpipe) conducts air; pharynx is the common passage for food and air; bronchi lead to lungs. The larynx is cartilaginous, and in males, the thyroid cartilage forms the Adam's apple.
