(3) by removing from CO,
(4) by removing from plastocyanin.
....please answer the question with proper explanation. ​

Answer 1

Answer:

By removing photon i.e H+ ion from water

Explanation:-

● It consists of two photoreactions, resulting in the synthesis of ATP and NADPH2.

● The hydrogen needed for the reduction of NADP (nicotinamide adenine dinucleotide phosphate) is made available from the breakdown of water.

■Therefore after breakdown of water 2 protons in the form of H+ ion are obtained thereby producing 2 electrons.

○Thus electrons are obtained by breakdown of water.
