A theoretical description of the simultaneous processes of photosynthesis and photorespiration in a single leaf is developed, based on the hypothesis that carbon dioxide and oxygen compete for the active site of ribulose diphosphate carboxylase. Michaelis-Menten kinetics and competitive inhibition at the end of a diffusion path provide the basic structure of the model. Data of Ludwig (1972) from sunflower are analyzed according to the formulation. This description is part of a more general physiological-ecological model of photosynthesis presented previously (Tenhunen et al., 1976a, b) and continues to elaborate sub-processes in terms of physiologically meaningful parameters. The description is considered a working hypothesis. Data on photorespiration from the literature are reviewed as they relate to this working hypothesis. Several lines of investigation are thereby suggested that will help clarify the role of photorespiration in whole leaf photosynthesis and determine the over-all utility of this modeling approach.
基于二氧化碳和氧气竞争二磷酸核酮糖羧化酶活性位点这一假设，构建了对单叶光合作用和光呼吸同步过程的理论描述。米氏动力学以及扩散路径末端的竞争性抑制构成了该模型的基本结构。根据此公式分析了路德维希（1972年）来自向日葵的数据。此描述是先前提出的更通用的光合作用生理生态模型（滕胡宁等人，1976年a、b）的一部分，并继续根据生理意义明确的参数详细阐述子过程。该描述被视为一个工作假设。本文回顾了文献中与该工作假设相关的光呼吸数据。由此提出了几条研究思路，这将有助于阐明光呼吸在全叶光合作用中的作用，并确定这种建模方法的整体效用。
