WebInhibition of Photosynthesis Inhibition at Photosystem II 1. General Information The popular misconception is that susceptible plants treated with these herbicides “starve to death” because they can no longer photosynthesize. In actuality, the plants die long before the food reserves are depleted. Webdirectly affects the rate at which photosynthesis can take place masking the effects of the other factors. Light and rate of photosynthesis At low light intensities, as light intensity increases, the rate of the light-dependent reaction, and therefore photosynthesis generally, increases proportionately (straight line relationship).

WebMay 25, 2024 · The electron transport chain is a series of molecules that accept or donate electrons easily. By moving step-by-step through these, electrons are moved in a specific direction across a membrane. The movement of hydrogen ions are coupled with this. This means that when electrons are moved, hydrogen ions move too. WebIn photosynthesis, carotenoids help capture light, but they also have an important role in getting rid of excess light energy. When a leaf is exposed to full sun, it receives a huge amount of energy; if that energy is not handled …
