Atrazine is an herbicide that prevents plant growth by inhibiting photosynthesis. Atrazine works by binding to proteins in the e

lectron transport chain of photosystem II. Once atrazine binds to the proteins, electrons can no longer travel down the chain to reach photosystem I.
Based on this information, how does atrazine stop plant growth?

A.
It prevents water from releasing oxygen, which is needed by the light-dependent reactions to fix carbon.
B.
It prevents the formation of NADH and FADH2, which are needed by the light-independent reactions to fix carbon.
C.
It prevents chlorophyll from creating electrons, which are needed by the light-dependent reactions to make sugars.
D.
It prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars.

It prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars. Thus, the correct option is D.

The herbicide atrazine binds to the D1 protein and prevents plastoquinone from binding. By preventing plastoquinone from binding, the photosynthetic transport of electron is disrupted, putting the generation of ATP and NADPH in the chloroplast at risk.

 

<h3>What are herbicide?</h3>

Herbicides are chemicals that are used to control or manage unwanted vegetation. Herbicides are most commonly used in row-crop farming, where they are treated before or during planting to increase crop productivity while reducing other vegetation.

This results in the plant's inability to fix carbon dioxide and provide the nutrients it needs to survive. A halt in electron transmission causes oxidative stress and the generation of radicals, which leads to rapid cellular death.
