Question

How are light-dependent reactions and light-independent reactions related?

Answer 1

Answer:

The light-independent reactions use the products of the light-dependent reactions

Explanation:

The light-dependent reaction produces carbon and hydrogen that are important in the light-independent phase. This light-dependent phase uses the energy from the sun to split a water molecule into H+ and O- (O- is evolved out of the plant). H+ is then used to reduce carbon dioxide. ATP is also produced through chemiosmosis - since a H+ gradient across the lamellae was created by the electron transpoirt chain.

The reduced carbon dioxide then enters the light-independent phase where it captured using malate. Carbon fixation process of the Calvin cycle then utilizes this carbon dioxide to produce carbohydrates. ATPs made in the light-depedent phase are also consumed here since this is an anabolic reaction.
