Question

Which of the following is formed during the light dependent reactions of photosynthesis?

• A. Glycolysis
• B. Calvin cycle
• C. ATP and NADPH${}_2$
• D. FADH${}_2$
• E. Electron transport chain

Answer 1

The correct option is C ATP and NADPH${}_2$

Light reaction occurs in the thylakoid membrane of the chloroplasts. It involves cyclic and non-cyclic photophosphorylation. Photophosphorylation is the production of ATP from ADP and H${}_3$PO${}_4$ in presence of light and chlorophyll-a during the photochemical phase of photosynthesis.

During cyclic photophosphorylation, ATP is produced and in non-cyclic photophosphorylation, ATP and NADPH${}_2$ are produced.

Hence, the products of the light reaction are ATP and NADPH${}_2$. So, the correct answer is ATP and NADPH${}_2$.
