The light-independent reactions of plants function to make organic molecules using carbon dioxide as a carbon source. What is the electron source that helps reduce carbon dioxide to sugars and other organic molecules?
A) NADH
B) NADPH
C) ATP
D) electrons from oxygen

Question

Quizplus · Accepted Answer

The electron source that helps reduce carbon dioxide to sugars and other organic molecules in the light-independent reactions is NADPH. NADPH is produced during the light-dependent reactions of photosynthesis and is used as a reducing agent in the Calvin cycle to convert carbon dioxide into organic molecules such as glucose.
