When does the DPIP turn green?

Question

What does the color green have to do with it? I am doing a photosynthesis lab and need help!! FAST!!!!!!! Thanx!!!

Answer 1

A detection mechanism for photosynthesis is DPIP (2, 6-dichlorophenol-idophenol). DPIP will become reduced before NADP+. DPIP, in its unreduced state, is blue in color but changes, when it is reduced, to clear, allowing a spectrophotometer to read the transmittance of the sample. Thus, if photosynthesis is occurring, DPIP will become clear.  

Answer 2

Ramya, no help from the internet!  You should be doing the quizzes from memory.
