The Calvin cycle in plants is responsible for the reduction of CO2 for synthesis of
a) Amino acids
b) Nucleotides
c) Hexose sugars
d) Cellulose
e) Urea

Respuesta :

Answer:

Option c) Hexose sugar

Explanation:

The Calvin cycle is carried out in three stages:

  • First stage includes carbon dioxide fixation with the help of 1,5-bisphosphate  and ribulose
  • Second stage includes the synthesis of Hexose sugar by reducing carbon dioxide
  • Third stage includes the regeneration of 1,5-bisphosphate  and ribulose.

The carbon dioxide molecule reacts with 1,5-bisphosphate and ribulose leading to the formation of an unstable compound of  six-carbon, which is further rapidly hydrolyzed to generate two 3-phosphoglycerate molecules.

Other ways of synthesizing hexose sugars by reducing Carbon dioxide in the photosynthetic world is the reverse mode of  citric acid cycle running.
