Open in App
Solution
The correct option is D Gibberellin
During seed germination, bioactive GAs are synthesized in the embryo and transported to the aleurone layer to induce α-amylase gene expression and α-amylase synthesis. Then, α-amylase is secreted into the endosperm to hydrolyse the stored starch.
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.
Lipase is the enzyme that increases the rate of hydrolysis of lipids into fatty acids.
So, the correct answer is "option B"
