What among the following would happen to plant exposed to toxin that made thylakoid membranes permeable to protons?  a reverasal of proton gradient across thylakoid membrans would result in higher pH in thylakoid lumen than the surrounding stroma reduction of NADP+ inthe chloroplasts would no longer be possible  the proton gradient across the ehylakoid membrane woudl be eliminated the transport of electrons by the protein complexes int eh thylakoids would be prevented.

Photosynthesis

Plants have a capacity that we humans can only imagine— the ability to produce food from sunlight. Sure, we can prepare some dishes that we can savor on, but it become possible because of the plants (as they serve as a producers of all the raw materials required). Photosynthesis is the method of assembling carbohydrates with the aid of sunlight.
