Which plant secretion are called amphibolic hormone .List their function

Dear student

Amphibolic hormone is the secretion which influences both catabolic and anabolic processes.
Ethylene is the plant secretion that acts as amphibolic hormone. It is involved in both catabolic and anabolic processes.

Functions

It helps in breaking seed and bud dormancy.

2. It promotes rapid internode-elongation in deep-water rice plants.

3. It promotes root-growth and formation of root hairs.

4. It promotes senescence and abscission of leaves and flowers.

5. It hastens the respiration rate in fruits and enhances fruit ripening.

Respiration is generally assumed to be a catabolic process because during respiration, various substrates are broken down for deriving energy. Carbohydrates are broken down to glucose before entering respiratory pathways. Fats get converted into fatty acids and glycerol whereas fatty acids get converted into acetyl CoA before entering the respiration. In a similar manner, proteins are converted into amino acids, which enter respiration after deamination.

During synthesis of fatty acids, acetyl CoA is withdrawn from respiratory pathway. Also, in the synthesis of proteins, respiratory substrates get withdrawn. Thus, respiration is also involved in anabolism. Therefore, respiration can be termed as amphibolic pathway as it involves both anabolism and catabolism.
