Which digestive enzyme breaks down lactose into glucose and galactose? MCQ with Answer and Explanation

Which digestive enzyme breaks down lactose into glucose and galactose?
A. Amylase
B. Lactase
C. Maltase
D. Sucrase
Answer: Option B
Solution (By JKExamLibrary)
Lactase is a brush border enzyme of the small intestine that hydrolyzes the disaccharide lactose (milk sugar) into its constituent monosaccharides, glucose and galactose. Maltase acts on maltose, sucrase on sucrose, and amylase on starch. Lactose intolerance results from lactase deficiency, causing gastrointestinal symptoms after dairy consumption.

Question #2
The pores present in the bark of woody stems for gaseous exchange are called:
A. Lenticels
B. Sclereids
C. Stomata
D. Hydathodes

Correct Answer: Option A


Explanation:
Lenticels are small, raised pores in the bark (periderm) of woody stems and roots that permit gas exchange between internal tissues and the atmosphere. Stomata are on leaves, hydathodes are for guttation, sclereids are sclerenchyma cells. Lenticels are filled with loosely arranged complementary cells and are visible as small dots on the surface of bark.

Question #3
The vector commonly used for cloning genes in plants is:
A. pBR322
B. Cosmid
C. Bacteriophage lambda
D. Ti plasmid

Correct Answer: Option D


Explanation:
The Ti (tumor-inducing) plasmid from Agrobacterium tumefaciens is a natural plant genetic engineer. It transfers T-DNA into the plant genome, making it an effective vector for introducing foreign genes in plant genetic engineering. pBR322 is a common E. coli cloning vector. Bacteriophage lambda and cosmids are used in animal/bacterial systems. Ti plasmid has revolutionized GM crop development.
