A suspension of freeze-thawed mitochondria mixed with purple membranes from Halobacteria was illuminated with visible light. It was found that the light exposure prevented inhibition of succinate oxidation. The illumination also led to a decrease in inhibition of the rate of ferricyanide reduction by rat liver mitochondria in the presence of succinate. Both phenomena are explained by the fact that oxalacetate inhibition of succinate dehydrogenase is prevented by light-induced energization of mitochondrial membranes due to the contact with purple membranes.
将冻融线粒体的悬浮液与嗜盐菌的紫色膜混合，用可见光照射。结果发现，光照可防止琥珀酸氧化受到抑制。在琥珀酸存在的情况下，光照还导致大鼠肝线粒体对铁氰化物还原速率的抑制作用减弱。这两种现象都可以通过以下事实来解释：由于与紫色膜接触，光诱导的线粒体膜能量化可防止草酰乙酸对琥珀酸脱氢酶的抑制。
