photosynthesis
Explanation / Answer
1) Option '4' : Photorespiration is the correct answer.
Photorespiration is a respiratory process in plants in which they take up oxygen in the presence of sunlight and give up carbon-dioxide in contrast to photosynthesis.
2) Option '5' : a series of hydrogen acceptors is the correct answer.
The chemical energy captured by chlorophyll A during photosynthesis is transferred to ATP and NADH or NADPH which are reduced electron carriers. Both are needed for carbon fixation reactions (the reduction of inorganic carbon to make organic carbon molecules)
3) Option '1' : both ATP and Oxygen is the correct answer.
Photosynthesis is the single most important process on earth. It is responsible for fixation of light energy of sun in form of chemical energy as ATP which is utilized to produce glucose which is the primary source of energy in all organisms on earth. Oxygen is released as a byproduct of photosynthesis. Without it, aerobic respiration and all metabolic processes involving oxygen would come to a standstill and life on earth will not survive as we know it.
