Question

Calvin cycle occur in [BHU 1983; MP PMT 1996; BVP 2002]
A) Chloroplasts
B) Cytoplasm
C) Mitochondria
D) Glyoxisomes

Answer 1

Dear Student,

● Answer - (A)

Calvin cycle occur in Chloroplasts.

● Extra information -

• Calvin cycle is known as light independent reaction / dark reaction.
• It takes place in chloroplast in presence of RuBisCo enzyme.
• Calvin cycle require ATP & NADPH for production of glucose.
• Though dark reactions are light independent, they must occur during the day.
• Usually Calvin cycle results in gain of 6 fixed C-atoms.

Thanks dear. Hope this helps you...

Answer 2

Calvin cycle occur in Chloroplast.

Option: A  

Explanation:

• It is also known as the C3 cycle. This cycle occurs during photosynthesis.  

• In this cycle, carbon dioxide is used. Hence carbon fixation takes place. Hence it is common fixation method.  

• By this cycle carbon dioxide is converted into carbon. Then it is converted to bio molecules which are utilized by organisms.  

• Also it is takes place in C3 cycle of the plant photosynthesis.  

• Carbon dioxide enters the leaves by small pores which is known as stomata.
