photosynthesis and O2 evolution

Can anyone inform me of the relationship between CO2 uptake and O2 evolution in photosynthesis?

Re: Photosynthesis/carbon fixing

No, the level of rubisco carboxylase. In the first example, rubisco carboxylase is normal level and the oxygen evolution is consistently higher than CO2 uptake. In the second example, rubisco carboxylase is at 40% its normal level. O2 evolution is again consistently higher than CO2 uptake. Both O2 e...

O2 evolution/CO2 uptake

In photosynthesis, what is the relationship between oxygen evolution and carbon dioxide uptake?

Re: Photosynthesis/carbon fixing

Yes, the second example is decreased to 40% and the third decreased to 10%.

Re: Photosynthesis/carbon fixing

Well, if the O2 evolution is consistently higher than CO2 uptake when the enzyme levels are normal or at 40%, but are not when the level is 10%, I found it reasonable to assume that the enzyme level had an affect on oxygen evolution.

Re: Photosynthesis/carbon fixing

Hello JackBean

Yes i made a mistake I did switch the axises thank you for noticing.

I thought that was the reason for the O2 levels being higher but in the third graph, the one with 10% the normal level, the O2 levels are consistent with CO2 and are sometimes lower, that is what confused me.

Photosynthesis/carbon fixing

Hello I am fairly new to plant biology and was hoping someone could point me in the right direction regarding a question in an assignment i am doing at this moment in time. It is about photosynthesis and carbon fixing, and although I understand the process and the complex stages involved, I cannot s...
