The O2 evolved during photosynthesis comes from
A.
PEP
B.
PGA
C.
CO2
D.
H2O
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
The O2 that evolved during photosynthesis comes from H2O.Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
Oxygen evolved during this process is evolved from the hydrolysis of water, and the hydrogen freed by the splitting of water is used in the creation of further compounds.
