During light reaction in photosynthesis the following are formed.

Options

A. ATP and sugar
B. hydrogen, `O_(2)` and sugar
C. ATP, hydrogen donor and `O_(2)`
D. ATP, hydrogen and `O_(2)` donor

Answer

C

Explanation

( c) Light dependent reaction uses solar power to generate ATP and `NADPH_(2)` which provide chemical and reducing power respectively to sugar synthesising reactio of the Calvin cycle, while the `O_(2)` in released as a by product of light dependent reaction. Other option are incorret because
(a) ATP is produced in light reaction but sugar is produced in dark reaction.
(b) `H_(2)` is produced by splitting of water `(H_(2)O to 2H^(+)+(1)/(2)O_(2))H^(+)` are released. The `2H^(+)` is accepted by NADP to form NADP to form NADPH and oxygen `(O_(2))` is of course produced by sugar is not.
( c) `O_(2)` donor and ATP is produced in light reaction but not the hydrogen.
