Solution:

Gibberellins, specifically Gibberellic acid (GA₃), are widely used in the brewing industry to speed up the malting process. They promote the synthesis of hydrolytic enzymes like amylase in the aleurone layer of barley grains, which helps in the breakdown of starch into fermentable sugars, thus accelerating germination and malt production.
