Question

All of the following statements are true about photosynthesis, except

• A. The light cycle occurs only during exposure to light.
• B. The dark cycle occurs only in the absence of light.
• C. ATP is produced during the light cycle.
• D. During the dark cycle, sugars are produced.
• E. Red and blue light are optimal for photosynthetic function.

Answer 1

The correct option is B The dark cycle occurs only in the absence of light.

Photosynthesis involves the light and dark reactions, The light reactions occur during the exposure of light and exposure to red and blue light show optimal functions. NADPH and ATP are the products of the light reaction. The products of the light reaction are used in the dark reaction for the production of sugar. The dark reactions can occur in the presence or the absence of light.

Thus, the correct answer is the option B
