Show Answer
Answer : c
Hints & Solutions
(c) Gibberellins stimulate the synthesis of $\alpha$-amylase and protease enzyme in germinating grains of cereals. They are involved in the conversion of starch into sugar. The proteases convert an inactive $\beta$-amylase to the active form. The active $\beta$-amylase and $\alpha$-amylase together digest starch to glucose which is mobilized to meet the metabolic demands of embryo.
