SSC MTS EXAM

Detailed explanation-1: -NADPH and ATP drive the second stage, the “dark” reactions (or Calvin cycle, discovered by Melvin Calvin), which do not require light. During this stage glucose is generated using atmospheric carbon dioxide.

Detailed explanation-2: -The dark reaction occurs outside of the thylakoids. In this reaction, the energy from ATP and NADPH are used to fix carbon dioxide (CO2). The products of this reaction are sugar molecules and other organic molecules necessary for cell function and metabolism.
