Question

Which statements is correct for given reaction for photosynthesis:-
${2H}_{2}A+C{O}_2\underrightarrow{light}2A+C{H}_{2}O+H_{2}O$

• A. H donor from $H_{2}O$ if reducible compound is $H_{2}O$
• B. $O_2$ evolve from $H_{2}O$ if a reducible compound is$H_{2}O$
• C. Glucose gain its oxygen from $H_{2}O$
• D. $\left(1\right)$ & $\left(3\right)$ both

Answer 1

Answer: (B)

$O_2$ evolve from $H_{2}O$ if a reducible compound is$H_{2}O$

The oxygen evolution is part of the light-dependent reactions of photosynthesis in cyanobacteria and the chloroplasts of green algae and plants. It utilizes the energy of light to split a water molecule into its protons and electrons for photosynthesis. Free oxygen, generated as a by-product of this reaction, is released into the atmosphere.

So, the correct option is 'O${}_2$ evolve from H${}_2$O if a reducible compound is H${}_2$O'
