Which of the following statements about the light reactions of photosynthesis is true? a. there are two distinct photosystems, linked together by a mechanism similar to electron transport. b. the source for electrons is located in the stroma of the thylakoid. c. the mn complex is the primary electron acceptor and is located on photosystem i. d. the ultimate electron donor is molecular oxygen. e. plastoquinone is a fixed electron transporter in the system located in the inner membrane

Option (A).

Explanation:

Photosynthesis may be defined as the process in which the light energy has been converted to the chemical energy so that plants can obtain their food with the help of sunlight, carbon dioxide and water.

Photosynthesis is divided into light reaction and dark reaction. The light reaction of photosynthesis is linked together by the mechanism which is similar to the electron transport chain of mitochondria.

Thus, the correct answer is option (A).

b is the best answer for this question.

weathering is the answer.
