Pronase-treated cells of Euglena gracilis Z show no discernible ultrastructural effects on the photoreceptor apparatus; however, there are physiological effects on swimming speed and on step-up and step-down photophobic responses, especially the latter. Pronase acts differently on the two photophobic responses: the step-down response is completely inhibited after 2 hr., whereas inhibition of the step-up response occurs in only 50% of the cells even after 24 hr. The effects are fully reversible, with step-up recovery quite rapid and step-down recovery considerably slower.
经链霉蛋白酶处理的纤细裸藻Z细胞对光感受器装置没有明显的超微结构影响；然而，对游泳速度以及上升和下降式避光反应有生理影响，尤其是后者。链霉蛋白酶对两种避光反应的作用不同：下降式反应在2小时后完全被抑制，而上升式反应即使在24小时后也只有50%的细胞受到抑制。这些影响是完全可逆的，上升式反应恢复很快，下降式反应恢复则慢得多。
