Question

Assimilatory power produced in Hill reaction and used in Blackman's reaction refers to

• A. Generation of ATP and NADPH${}_2$
• B. Reduction of CO${}_2$
• C. Splitting of water
• D. Disintegration of plastids

Answer 1

The correct option is A Generation of ATP and NADPH${}_2$

Light reaction or light dependent reaction or Hill's reaction occurs in grana of chloroplast where the energy from sunlight is absorbed and converted to chemical energy which is stored in ATP and NADPH${}_2$
In light-independent reactions or Blackman's reaction, the carbohydrates are synthesized from carbon dioxide using the energy stored in the ATP and NADPH${}_2$ formed in the light-dependent reactions.

Assimilatory powers (ATP and NADPH${}_2$) are mainly produced in the light reaction.

So the answer is 'Generation of ATP and NADPH${}_2$.
