Question

While reading an online resource, a student noticed an error in the paragraph below: In photosynthesis, ATP is generated in the light reactions and used in the light-independent reactions as a reducing agent to reduce carbon dioxide to form carbohydrates, which the plant can use for structure and energy. Which word or phrase could be changed to eliminate the error?
a. ATP
b. Light-independent reactions
c. Reducing agent
d. Carbon dioxide
e. Structure

Answer 1

Answer:

The correct answer is c reducing agent.

Explanation:

Photosynthesis consist of both light reaction and dark reaction.The light reaction result in the formation of ATP and NADPH.The so formed ATP and NADPH are used in dark reaction to fix CO2 resulting in the production of glucose.The principle of ATP to provide energy to carry out the CO2 fixation process of dark reaction.

            NADPH act as a reducing agent that reduces the phosphoglyceric acid(PGA) into phosphoglyceraldehyde(PGALD).
