The question is:

 "Which of the following statements is correct about cyclic phosphorylation?" 

 A) ATP is produced by light energy.  

B) This process occurs when a chloroplast runs low on ATP.  

C)Both NADPH and ATP are produced during this process.  

D) Only P680 is directly involved in this process, not P700.  


Which one should I choose and why? thanks!

Hi Iris,

We reached out to Mr. Pellegrino about this question. He said that "The answer is choice A. It is a method of ATP production. Also please note it is not necessary knowledge for the AP exam."

Hope this at least helps a bit!
