Question

during light reaction of photosynthesis , how many protons are required for evolution of one O2 molecule
​

Answer 1

Answer:

co2 and o2 ka process ok

Answer 2

Photosynthesis

Explanation:

• Photosynthesis starts with the light responses.The vitality is then briefly moved to two particles, ATP and NADPH, which are utilized in the second phase of photosynthesis.
• ATP and NADPH are produced by two electron transport chains. During the light responses, water is utilized and oxygen is delivered.  
• In noncyclic electron transport in chloroplasts, four electrons make one oxygen particle and two NADPH atoms, and a similar four electrons siphon a sum of 12 protons into the thylakoid lumen from the stroma.  
• Photosystem II discharges protons into the thylakoid lumen and takes them up from the stroma. The outcome is a pH slope over the thylakoid film with an abundance of protons (low pH) inside.  
• They are given to P680+ individually when the electron are taken by the mn complex.
• The net aftereffect of this response is the creation of  the photolysis of  water 2 ATP and 9 NADPH .
• The  NADPH and ATP will be utilized in the Calvin-Benson-Bassham pattern of the dim responses.
