Question

An enzyme that can stimulate the germination of barley seeds is
(a) Protease
(b) Invertase
(c)$\alpha$-amylase
(d) Lipase

Answer 1

This enzyme is responsible for the hydrolysis of alpha bonds of large alpha linked polysaccharides such as glycogen, starch, glucose, maltose, etc.

Complete answer:
Alpha-amylase is the enzyme that can stimulate the germination of barley seeds. The enzyme alpha-amylase mobilizes the stored nutrients in the seeds. Germination of seeds is indicated by the emergence of roots. The temperature required during the growth period of barley is around 12 to 15 degrees Celsius, whereas the temperature required at maturity is 30 to 32 degrees Celsius. The enzyme alpha- amylase is present in the seeds containing starch as stored food.

Additional Information: -The barley seeds are a rich source of gibberellin protein, the hormone responsible for conducting germination, stem elongation, dormancy, flowering, flower development, leaf and fruit sentence. -First of all the seeds are soaked in water for a long time so that it can absorb maximum water.
-Once the water is imbibed in the seeds the gibberellins are released from the embryo.
-This signals the seed to break dormancy and germination. This breakdown of dormancy occurs at the exposure to light and at low temperatures.
-By stimulating the synthesis of digestive enzymes such as alpha-amylase, the gibberellins support the growth of seedlings.
-Protease is the enzyme that increases the rate of the breakdown of proteins into amino acids. They are present in the stomach and pancreas of humans and play a vital role in protein digestion.
-Invertase is the enzyme that is responsible for the hydrolysis of sucrose into glucose and fructose. These are used to make candy liquid centers, chocolate-covered cherries, fondant candies, creme eggs, and other cordials.
-Lipase is the enzyme that increases the rate of hydrolysis of lipids into fatty acids.
So, the correct answer is '$\alpha$-amylase'.

Note: -Germination of barley seeds begins when it absorbs water and ends with the appearance of the radical in the seeds.
-The enzyme alpha-amylase mobilizes the stored nutrients in the seeds.
-Barley can be grown as both summer or winter crops. Both tropical and subtropical climates are suitable for barley's growth.
