Photosynthesis can be divided into two part: light reaction is the first stage of photosynthesis, occurring only in the presence of light, during which energy captured from light drives the production of ATP.

dark reaction is the second stage of photosynthesis, not requiring light to occur, and during which energy released from ATP drives the production of organic molecules from carbon dioxide.

How are light reactions and dark reactions different and similar?

Differences: >light reactions occur in the thykaloid membranes, but dark occur in stroma >light reactions are light dependent, or they need light to take place, whereas dark reactions don't > dark reactions use the products of the light reactions >light reactions are the first step of photosynthesis and dark reactions are the second step Similarities: >both in photosynthesis Thats really the only similarity!!! hope this helps :)


Where does the oxygen produced in the dark reaction of photosynthesis come from?

It is obtained from air. Oxygen is not is not produced in dark reaction but in light reaction


What is the the process of plant respiration?

the respiriration is such a oxidative reductive process ... and during plant it have two complex more process consist of seriese of steps DARK reaction and Light reaction.................... dark reaction need no light wheather in day time or night time...................... some how the light reaction are done in the prescence of light ..........during the light reaction the formation of the light reaction is just one ATP Which is responsible for the production of dark reaction .............
