Question

What are the products of light-dependent reactions? Why are they important in light-independent reactions?

Answer 1

Answer:

The two products of the light-dependent reactions of photosystem are ATP and NADPH. The movement of high energy electrons releases the free energy that is needed to produce these molecules. The ATP and NADPH are used in the light-independent reactions to make sugar.

Answer 2

     

   →   Products of light-dependent reactions:

• As we know that light-dependent reactions produced ATP, NADPH, and O2 by breaking water molecules.

• It depends upon light, it requires sunlight to produce ATP, NADPH, and O2.

• The light-dependent reactions convert light energy into chemical energy.

• As we know light-depended reactions occur in thylakoids.

       

   →   ATP, NADPH is important in light-independent reactions:

• ATP and NADPH from the light-dependent reactions are used by the light-independent reactions.

• To convert the energy to the chemical bond energy in carbohydrates such as glucose and reduce carbon dioxide.
