Question

4. The light-independent reaction uses the energy from _________ to produce _________.

Answer 1

Answer:

The light- independent reaction uses the energy from NADPH and ATP to produce Sugar.

Explanation:

The end product of light- independent reaction is sugar (glucose) which is made from carbon dioxide.  The energy for these comes from the end results of light- dependent reactions .

This includes NADPH and ATP. This process is termed as the Calvin Cycle.

Steps of the Calvin Cycle include:

1. The formationof a six carbon sugar , Phosphoglycerate, by combination of a five carbon sugar, Ribulose biphosphate (RuBP) and Carbon dioxide.

2. The formation of two molecules of Triose Phosphate by reducing Phosphoglycerate using hydrogen atoms of the light- dependent reactions. This reaction uses ATP.

3. ATP is also used  to convert some of the Triose Phosphate back to RuBP.

4. GLUCOSE is produced using the rest Triose Phosphate.
