Who's correct? My professor or Mr. Mistery???

[binoo]

This is about PHOTOSYNTHESIS.
My professor taught us that the Terminal Electron Acceptor for Photosynthesis is "NADP+", but a few days ago someone named "Mr. Mistery" from this forum had posted that the Terminal Electron Acceptor for Photosynthesis is "OXYGEN".
Who's right?
I'm confused.
Please HELP ME.
THANK YOU!!!

in this case ur professor is right, however i dont think mr mistery would make that mistake. oxygen is indeed the terminal electron acceptor of aerobic respiration. a misunderstanding, perhaps?

where is this post? link please?

I believe an electron donor on photosynthesis is H2O. Then what would be the terminal e- acceptor for photosynthesis? Is it "electron transport chain"??? Does anyone know the answer?
Thank you so much in advance.

Donor of elector (aqua) => chlorophill => acceptor of electron - pheophetin (photosynthetic pigment)

by the way, where's Mr M?

[mith]

I'd say it's a misunderstanding, the electron acceptor for aerobic respiration is oxygen but for photosynthesis is nadp.

Mr M is prolly going to be busy these couple of weeks, he's studying for a competition.

yup, I think like that also about him (MrM)...studying with lots of questions.....

[2810712]

When the e- goes down the Energy gradient...the last member is NADP- which the forms [NADPH] + [H+]...so its NADP- i say...

then this NADP goes to stroma and then acts as energy donor...there also redox reaction occurs... so the real terminal reaction is differnt...

correct me whereever possible & ASAP.
