14/02 A proton with a mass of 1.6726219 x 10^-27 kg and a charge 1.602 x 10^-19 Clies between two charged plates that produce a uniform f
ield of 1000 Vm^-1. It is moved 10cm towards the positive plate. Is the work done on the proton positive or negative?​

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.

I'm pretty sure the answer is c
