What energy-rich compounds do the light reactions produce?

Question

A. ADP
B. ATP
C. Glucose
D. NADPH
E. ATP Synthase

Answer 1

The light reactions of photosynthesis remove electrons from water (forming oxygen) and transfers those electrons through an electron transport system onto NADP to form NADPH. As the electrons pass through the electron transport system, protons are pumped into the thylakoid membranes which drives the synthesis of ATP.

So the best answer is BOTH B AND D.

Answer 2

light reactions will produce ATP and NADPH, but as an end product plants will produce glucose:
Photosynthesis uses the energy of light to make the sugar, glucose. A simple general equation for photosynthesis follows.

6CO2 + 6H2O + light → C6H12O6 + 6O2
carbon dioxide + water + light energy → glucose + oxygen
So dependes if the question refer to specific chlorophyl activity, or general plant activity
