Question

The light reactions of photosynthesis use _____ and produce _____. The light reactions of photosynthesis use _____ and produce _____. water ... NADPH NADPH ... NADP carbon dioxide ... oxygen NADPH ... oxygen carbon dioxide ... sugar

Answer 1

Input = $NADP^+$, water and Output = $NADPH + O_2$

Explanation:

The light reactions of photosynthesis use water and produce Oxygen, NADPH.

The equation for photosynthesis :

$6 CO_2 + 6 H_2O$ → $C_6H_12O_6 + 6 O_2$

The process of photosynthesis in two stages -

• The first stage is called the light reaction in which the light energy from the sun is captured and converted into chemical energy stored in the form of ATP and NADPH

• The second stage is the process of conversion of ATP molecules to sugar or glucose (the Calvin Cycle)

For a light reaction -

Net Input is of, $NADP^+$, $Light, Water, ADP$

Net Output is of, $ATP, NADPH, O_2$
