The photosynthetic dark reactions ________.
A)occur only in the dark (nocturnal)
B)are the main source of ATP in photosynthesis
C)convert carbon dioxide to carbohydrates
D)produce the reduced coenzyme NADH

Question

Quizplus · Accepted Answer

The photosynthetic dark reactions, also known as the Calvin cycle, convert carbon dioxide into carbohydrates. This process occurs in the stroma of the chloroplast and is fueled by the ATP and NADPH produced during the light reactions. The dark reactions do not occur only in the dark, as the name might suggest, but can occur in light as well. The main source of ATP in photosynthesis is the light reactions, not the dark reactions. The dark reactions also do not produce NADH, but rather use NADPH as a reducing agent.
