Thuốc trừ sâu ảnh hưởng với quá trình quan trọng cho tất cả các sinh vật Sản xuất năng lượng trong ty thể và các cơ chế đằng sau phân chia tế bào là rất giống nhau trong tất cả các sinh vật có nhân điển hình. Hơn nữa, một số chất ức chế enzyme có rất ít đặc hiệu mà nhiều enzym khác nhau trong một loạt các sinh vật có thể là mục tiêu. Nhiều người trong số các thuốc trừ sâu với các chế độ chung của hành động có quan tâm đến lịch sử đáng kể. Không. | chapter three Pesticides interfering with processes important to all organisms Energy production in mitochondria and the mechanisms behind cell division are very similar in all eukaryotic organisms. Furthermore some inhibitors of enzymes have so little specificity that many different enzymes in a great variety of organisms may be targets. Many of the pesticides with such general modes of action have considerable historic interest. Not all of them are simple in structure and many are used for purposes other than combating pests. Pesticides that disturb energy production Anabolic and catabolic processes Green plants are anabolic engines that produce organic materials from carbon dioxide other inorganic substances water and light energy. New organic molecules are made by anabolic processes whereas organic molecules are degraded by catabolic processes. Plants are also able to degrade complicated organic molecules but the anabolic processes dominate. Animals bacteria and fungi may be called catabolic engines. Their task is to convert organic materials back to carbon dioxide and water. Most of the energy from the catabolism is released as heat but much is used to build up new molecules for growth and reproduction. Almost all of the energy required for these many thousand chemical reactions is mediated through adenosine triphosphate ATP which is broken down to adenosine diphosphate ADP and inorganic phosphate in the energy-requiring biosynthesis. ADP is again rebuilt to ATP with energy from respiration and glycolysis. The basic catabolic processes that deliver ATP are very similar in all organisms and are carried out in small intracellular organelles the mitochondria. We should suppose therefore that pesticides disturbing the processes are 2004 by Jorgen Stenersen not very selective which is indeed the case. We find very toxic and nonse-lective substances such as arsenic fluoroacetate cyanide phenols and organic tin compounds but also substances with some .
