Increasing levels of CO(2) have been shown to stimulate the rate of photosynthesis, eliminate the oxygen inhibition of photosynthesis (Warburg effect), and decrease glycolate formation in isolated spinach chloroplasts. Ribose 5-phosphate and fructose 1,6-diphosphate at concentrations of 5 to 10 mum also stimulate the rate of plastid photosynthesis and eliminate the Warburg effect. In contrast to the effect of high CO(2) levels, these sugar phosphates have little effect on glycolate formation. Evidence is presented to show that the level of intermediates of the photosynthetic carbon reduction cycle may influence the Warburg effect in vivo. It is postulated that the formation of glycolate is not the causal factor of the Warburg effect.
已有研究表明，二氧化碳水平升高会刺激光合作用速率，消除光合作用的氧抑制作用（瓦伯格效应），并减少离体菠菜叶绿体中乙醇酸的生成。浓度为5至10微摩尔的5-磷酸核糖和1,6-二磷酸果糖也会刺激质体光合作用速率并消除瓦伯格效应。与高二氧化碳水平的影响相反，这些糖磷酸盐对乙醇酸生成的影响很小。有证据表明光合作用碳还原循环中间产物的水平可能会在体内影响瓦伯格效应。据推测，乙醇酸的形成不是瓦伯格效应的因果因素。
