Which of the following statements regarding photosynthesis is true?

Core Concept

The primary reason for the formation of the light-dependent reactions is to produce ATP and NADPH through light-dependent electron transfer. This energy is then used to drive the light-independent reactions (Calvin cycle), which produce glucose. Option A is incorrect because photosynthesis produces ATP, not requires it. Option C is incorrect because the Calvin cycle produces glucose, not oxygen. Option D is incorrect because the electron transport chain is involved in the production of ATP during photosynthesis.
