Energy is required for both the light-dependent and light-independent reactions to proceed. Thus, the correct option is A.
What is a Light-dependent reaction?
A light-dependent reaction may be defined as a reaction in plants that occurs in the presence of sunlight. It utilizes the direct use of light (photons) as a source of energy.
The light-dependent reaction occurs in the thylakoid membrane of the chloroplast. The final products of this reaction are ATP and NADPH.
The light-independent reaction also occurs in the presence of light but it does not utilize the direct source of light. It occurs in the stromal part of the chloroplast. Here, Rubisco is involved as a source of energy. The final product is carbohydrates.
Therefore, Energy is required for both the light-dependent and light-independent reactions to proceed. Thus, the correct option is A.
