Question
Which branch of biology deals with the study of fungi?
A. Pteridology
B. Mycology
C. Bryology
D. Phycology
Answer: Option B
Solution (By JKExamLibrary)
Mycology is the study of fungi, including yeasts and molds. Phycology deals with algae, bryology with mosses and liverworts, and pteridology with ferns. Fungi are eukaryotic, heterotrophic organisms with chitinous cell walls. The term mycology derives from Greek 'mykes' meaning mushroom. Alexander Fleming's discovery of penicillin from the fungus Penicillium notatum revolutionized medicine. Mycology is crucial for understanding fungal diseases and antibiotic production.

Correct Answer: Option A

Explanation:
Pancreatic juice contains inactive enzymes like trypsinogen, chymotrypsinogen, and procarboxypeptidase. When trypsinogen enters the small intestine, it is activated into trypsin by the enzyme enterokinase (secreted by the intestinal mucosa). Trypsin then digests proteins into smaller peptides. Pancreatic amylase digests carbohydrates, and lipase digests fats.
