The voice box or sound-producing organ in humans is the:
A. Larynx
B. Bronchi
C. Pharynx
D. Trachea
Answer: Option A
Solution (By JKSSB Mock Tests)
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.
Explanation:
Proteomics involves large-scale study of proteins, their structures, and functions. Genomics is DNA, transcriptomics RNA, metabolomics metabolites.
Explanation:
The Cell Theory was proposed by Matthias Schleiden (1838) and Theodor Schwann (1839). Schleiden concluded that all plants are composed of cells, while Schwann extended this to animals, stating that all living organisms are composed of cells and their products. Rudolf Virchow later added that all cells arise from pre-existing cells.
Explanation:
Adenosine triphosphate (ATP) is the universal energy currency of the cell, storing energy in its high-energy phosphate bonds. Hydrolysis to ADP releases energy for cellular work. NADH and FADH₂ are electron carriers in respiration, ultimately used to produce ATP. Glucose is a fuel molecule, broken down to produce ATP. ATP is directly used in processes like muscle contraction and active transport.
