Gibbane ring skeleton in structure and production of hydrolytic enzymes in barley endosperm is a characteristic of

Which one of the following structures is exceptionally rich in hydrolytic enzymes?

Define enzyme. Describe in brief the structure and characteristics of enzymes.

Make corrections wherever you find mistake in spellings/words in the following parapraphs/sentences. (A) During the period of senescence, a gradual addition occurs in the structure and functioning of an organ or organism which is characterised by the accumulation of active metabolic materials and increase in dry weight. (B) When the movement of curvature is produced by diffused stimuli and affects the whole plant uniformly, it is of tropic type. If the curvature is produced by directional mutimuli and does not affect the whole plant, it is of nastic type. (C) Shoot elongation in some dwarf varieties and barley endosperm test are used as bioassays for auxins and Avena curvature test is used as bioassay for ethylene.

Assertion : Gibberellic acid increases the yield of malt from barley grain. Reason :Gibberellins stimulate the synthesis of amylase, protease and other hydrolytic enzyme for mobilisation of reserve food.
