Photophoshorylation

Question 1

Depends on?

Answer 1

Flow of electrons from P680 and P700

Question 2

What happened to the electrons?

Answer 2

Boosted to a higher energy level by transfer of light energy from light harvesting complex to the reaction centre

Question 3

What happened to the excited electron?

Answer 3

Accepted by Pri electron acceptors; and Pri electron acceptors are reduced and photosystem are oxidised

Question 4

Flow of electron?

Answer 4

• Electrons are passed from one electron carrier to another electron carrier in ETC
• e carriers pump H+ into thylakoids space for proton gradient to drive ATP production
