The oxygen produced during phtosynthesis comes from photolysis of water was first time proved by

Options

A. Rubben and Kamen
B. Robert Mayer
C. Malvin Calvin
D. Blackman

Answer

A

Explanation

Photolysis occur in pressence of light quanta and requires `Mn^(+ +)` and `Cl^(-)` ions as catalyst for water oxidising.
`4H_(2)Ooverset(Mn^(+ +)Cl^(-))to4(OH)^(-)+4H^(+)`
Then H radicle forms water and `O_(2)` as a by product `4OHto2H_(2)O+O_(2)uarr`
