Question

When light strikes chlorophyll molecules in the reaction-center complex, they lose electrons, which are ultimately replaced by
a. splitting water.
b. oxidizing NADPH.
c. the primary electron acceptor.
d. the electron transport chain.

Accepted Answer

Hello everyone here we have a question saying the light reaction undergoes the falling stages except a absorption of light by chlorophyll. Light reactions needs light energy to make two molecules needed for the next stage of photosynthesis and this energy from the sunlight is absorbed by chlorophyll. So A. Is incorrect. Be production of glucose, glucose is produced in the Calvin cycle. The Calvin cycle is the second stage of photosynthesis, but it is not in the light reactions. So bee is correct. See the production of A. T. P and N A. D. P. H. In light reactions, the solar energy is converted into chemical energy in the form of electron carrier molecule which is A N A. D. P. H. And the energy currency molecule which is A. T. P. So C. Is incorrect D splitting of water in our light reactions. The water is oxidized and the oxygen is released and these electrons that are liberated when this happens are transferred to A T. P and N A. D. P. H. This is also called the photo analysis of water and water acts as a reducing agent that provides hydrogen ions and converts N A. D. P to N A. D. P. H. So D. Is incorrect. So our answer here is the production of glucose. Thank you for watching. Bye.
