The correct answer is - Its electrons are used to form NADPH. 
On receiving light energy, electrons are expelled from the reaction center of photosystem II. The expelled electrons finally reduces oxidized NADH⁺ to NADH. The oxidized reaction center of photosystem II split water into protons, electrons and oxygen. The electrons released from water reduces oxidized reaction center of photosystem II. Thus, oxidized reaction center of photosystem II gets back its expelled electrons. Therefore, electrons from water forms NADH. 
 
        
                    
             
        
        
        
Evolutionary theory predicted that bacterial resistance would happen. Given time, heredity and variation, any living organisms including the bacteria will evolve when a selective pressure, in this case an antibiotic is introduced. However it also gives doctors an patient some specific strategies for delaying even more widespread evolution of antibiotic resistance; these strategies include; avoid mild doses of antibiotics over long time periods, don't use antibiotics to treat viral infections, when treating bacterial infection with antibiotics, take all the pills, and also using combination of drugs to treat a bacterial infection.
