Difference between light dependent reactions and light independent reactions in photosynthesis?

Answer 1

I'm assuming you're talking about photosynthesis. The main difference can be seen in the terms. Light dependent need light to react, light independent do not. In the light reactions the photon of light hits the chlorophyll which excites an electron that goes into the electron transport chain. This electron comes from water being split into H+ ions and oxygent gas. A small amount of ATP is produced and NADPH is produced. In the dark reaction, called the Calvin cycle, the ATP and NADPH produced by the light reaction is used to combine RUBP with CO2 to make glucose.

Answer 2

The light-dependent reactions of photosynthesis occur in the thylakoid membrane and require light energy to produce ATP and NADPH. The light-independent reactions (Calvin cycle) occur in the stroma and use ATP and NADPH to convert carbon dioxide into glucose.

Answer 3

well it jflasjdfsjf;jfkasjfljaslfdjsa;lfjdsldjflsa

and that is the difference

Answer 4

in the presence of light reaction gots extra energy and in absence energy is low as compared to light dependent reaction

Answer 5

One of them is dependent on light, and the other isn't. If you want a better answer, ask a better question.
