Q. Calvin cycle proceeds in three stages
1. Reduction, during which carbohydrate is formed at the expense of the photochemically made ATP and NADPH
2. Regeneration, during which the carbon dioxide acceptor ribulose-1, 5-biphosphate is formed
3. Carboxylation, during which carbon dioxide combines with ribulose-1, 5-biphosphate
Identify the correct sequence

KEAMKEAM 2006Photosynthesis in Higher Plants

Solution:

Clavin cycle has three stages:
3. Carboxylation during which $CO_2$ combines with $1,5$ RuBP.
1. Reduction during which carbohydrate is formed at the expense of photochemically made ATP and NADPH.
2. Regeneration during which carbon dioxide acceptor $1, 5-RuBP$ is formed.
