Ethylene
is a growth hormone which is generally different from those of other
hormones such as auxin, gibberellin and cytokinin. Under normal circumstances, be in the form of gases Ethylene (C2 H4) with a chemical structure very simple.
Ethylene is produced during respiration of fruit, leaves and other tissues in plants. Because produced by plants in large amounts of this hormone can accelerate the ripening of fruit. Speed ripening fruit grown there are substances encourages solving hoarding flour and sugar. The
process of solving the flour and sugar accumulation is a cooking
process that is characterized by changes in color, texture and smell of
the fruit.
The
process of protein synthesis occurs in the maturation process of
natural or hormonal glance, where the protein is synthesized as soon as
the process of maturation. Fruit
ripening and inhibited by protein synthesis in the early phase
siklohexamin klimatoris after siklohexamin missing, then the synthesis
of ethylene not have problems. Synthesis of ribonucleic also required in the process of maturation. Ethylene enhances the synthesis of RNA on a green mango.
Ethylene is a growth hormone that is produced from normal metabolism in plants
In fruit ripening, ethylene working to solve the chlorophyll in young fruit, so the fruit has only xantofil and carotene. Thus,
the color becomes orange or red fruit . Ethylene produced by higher
plants from the essential amino acid methionine in all plant tissues. Production
of ethylene depends on the type of tissue, species, and stage of
development . Ethylene working to solve the chlorophyll in young
fruit, so the fruit has only xantofil and carotene. Thus, the color becomes orange or red fruit Ethylene is formed from methionine via the 3 processes :
• ATP is an important component in the synthesis of ethylene. ATP and water will make methionine lost 3 phosphate groups.
•
1-Amino-1-carboxylic aminosiklopropana synthase (ACC synthase) and
facilitates the production of ACC and SAM (S-adenosil methionine).
• Oxygen required to oxidize ACC and ethylene production. This reaction is catalyzed using ethylene-forming enzyme.
I want to ask
BalasHapuswhether the use of carbide in fruits can cause side effects in our body?
and whether fruits using carbide was still healthy and safe for consumption?
I will to try answer your question about carbide that Carbide can also be used to ripen fruit. Because carbide reacts with water will produce acetylene gas, which can also speed up the process of artificial ripening. However, the use of carbide often leave traces of arsenic and phosphorus which makes it hazardous to human health. So the use of calcium carbide to ripen fruits purposes is illegal in most countries.
HapusWhat are the dangers of arsenic and phosphorus caused to our bodies?
BalasHapusLike u said before?
I'll try to answer your question again.
BalasHapusArsenic is chemically similar characteristics with Phosphorus, and is often used as a substitute in a variety of biochemical reactions and also toxic. When heated, arsenic will rapidly oxidized to arsenic oxide, which smell like the smell of garlic. Arsenic and some arsenic compounds can also be instantly sublimated, changing from a solid to a gas without becoming liquid first.
If it is in the form of the element, the arsenic is harmless. But if in the form of oxides, namely arsenic dioxide, it is toxic in the form of a white powder and dissolves in water. Arsenic is tasteless and difficult to detect. Food or drink will not taste mixed with arsenic. The compound is used to be called 'inheritance powder' because it is used to kill people in order to get his inheritance and death is usually considered normal.
Symptoms of acute arsenic poisoning can occur in two forms. The first resulted in severe paralysis can occur within 1-2 hours and usually are marked with signs of delirium or insanity. While the second in digestive disorders such as nausea, headache, severe pain, vomiting and diarrhea.
A person who is exposed to this substance in a non-lethal dose, the future can lead to chronic toxicity and carcinogenic (cancer causing substances). Therefore arsenic is still a debate on the safety of workers in the industry are still using arsenic as an insecticide or weed exterminator company and extraction of tin and copper ore.
