Question

During the germination of castor seeds, the activity of ................. is very high.

• A. $\alpha$-amylase
• B. $\beta$-amylase
• C. Protease
• D. Lipase

Answer 1

Answer: (A)

$\alpha$-amylase

During the germination of castor seeds, the activity of $\alpha$-amylase enzyme is very high. Amylase is a protein enzyme that hydrolyses $\alpha$-bonds of large, $\alpha$-linked polysaccharides, such as starch and glycogen, yielding glucose and maltose. It is the major form of amylase found in humans and other mammals. It is also present in seeds containing starch as a food reserve, and is secreted by many fungi.
