SOME EFFECTS OF 2537 Å ON GREEN ALGAE AND CHLOROPLAST PREPARATIONS

Abstract

1. The kinetics of the inactivation of photosynthesis by 2537 Å in Chlorella pyrenoidosa and Scenedesmus D₁ indicate that, while the destruction process is largely a first order effect, higher order effects also occur, which become evident at low exposures. In agreement with previous observations, endogenous respiration is insensitive to exposures which inactivate photosynthesis.
