These electrons move through structures in chloroplasts and by chemiosmosis, make ATP. The hydrogen is converted to NADPH which is then used in the light-independent reactions. Oxygen diffuses out of the plant as a waste product of photosynthesis. This all happens in the grana thylakoid of chloroplasts.
Moreover, what happens in the light Dependant stage of photosynthesis?
The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.
What happens in the light stage of photosynthesis?
Thus, light energy is initially converted to chemical energy in the form of two compounds: NADPH, a source of energized electrons ( "reducing power"); and ATP, the versatile energy currency o that the light reactions produce no sugar; that happens in the second stage of photosynthesis, the Calvin cycle.
What is the location of the light dependent stage of photosynthesis?
The overall function of light-dependent reactions, the first stage of photosynthesis, is to convert solar energy into chemical energy in the form of NADPH and ATP, which are used in light-independent reactions and fuel the assembly of sugar molecules.
