摘要
本文提出了呼吸代谢是生物体内寓同化于异化的基本生理功能的新概念。论证了呼吸代谢与细胞生命系统自组织的关系。探讨了呼吸代谢通过多条途径对植物异养细胞能力系统的整合与调控,光呼吸对自养细胞光合作用的反馈作用,以及在靶细胞中呼吸作用受植物激素的调节。
A new concept of respiratory metabolism is proposed, which regards this process as ana-bolism involved in catabolism, and as the basis of self organization in living cells. In addition to furnishing material and energy for the performance of the plant as a living organism, it regulates the other physiological functions via the operation of multiple pathway. Based on the proposed concept, a bioenergetic system in heterotrophic plant cells is described, which comprises proticity, reducing powers and water motive force, a newly coined term by the authors, generated by respiration. The feed back effects of photorespiration, or in a broad sense, pho-toxidation on photosynthesis are discussed. An analysis of regulatory effects of phytohormones on respiratory pathway is also attempted.
