Question

Which of the following events does NOT take place in the light reactions?

A) Transfer of electrons to the reaction center of photosystem I
B) Conversion of 3PG to G3P
C) Generation of NADPH from NADP+
D) Splitting of water, releasing an electron
E) Generation of ATP from ADP + Pi

Answer 1

Answer:Conversion of 3PG to G3P

Step-by-step explanation:

Answer 2

B) Conversion of 3PG to G3P

Step-by-step explanation:

Conversion of 3PG (3 phosphoglycerate) or 3 phosphoglyceric acid is a reduction reaction step of the Calvin cycle, it does not take place during light reaction of the photosynthesis. The 3PG is converted into molecules of glyceraldehyde-3-phosphate (G3P) using ATP and NADPH. Generation of NADPH from NADP+, Photolysis or splitting of splitting of water that releases an electron and synthesis of ATP from ADP + Pi occurs during light reactions.
