Abstract:
This study investigated the growth, apoptosis and oxidative stress of the cyanobacterium Microcystis viridis exposed to glyphosate. Results showed that growth parameters, namely, cell destiny, chlorophyll a content, and protein content, were affected by glyphosate. The viability of the treated cells was monitored to further investigate the toxicity of glyphosate on M. viridis. After 24 and 48 h of exposure, glyphosate enhanced superoxide dismutase (SOD) activity and decreased malondialdehyde (MDA) concentration. The decrease in the MDA concentration might be caused by the enhanced SOD activity. This study helped elucidate the toxic effects of glyphosate on cyanobacteria and contributed to environmental assessment and protection.

Pyruvate Oxidation
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...
