Which reactions in photosynthesis require light?
Light dependent ...... Mr.Walcott is my biology teacher and she sucks at teaching so I have to research all the answers
The Calvin cycle of photosynthesis, which produces PGAL by fixing carbon from carbon dioxide which eventually makes glucose, is known as the "dark reactions" of photosynthesis since it does not directly need light. However, the Calvin cycle does require NADPH and FADH produced from the "light reactions" of photosynthesis. Therefore, technically no part of photosynthesis can occur without light.
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 :)
