Question

Which high-energy molecule and electron carrier are produced by the light reaction of photosynthesis?

Answer 1

The light reactions use solar energy to make ATP and NADPH, which funcrtion as chemical energy and reducing power respectively, in the Calvin cycle

Answer 2

Answer:

The correct answer is NADPH and ATP.

Light reaction of photosynthesis takes place in the thylakoid membrane of the chloroplast. The photosystem II uses light energy to cause photolysis of water molecule which releases high energy electrons and oxygen.

The electrons are then passed through the electron transport chain present in the same membrane and leads to the production of NADPH and ATP.

NADPH and ATP are high-energy molecules which carry and pass electrons to the dark or Calvin reaction which leads to the production of sugar.
