Question

Why kelvin cycle is known as c3 cyclce

Answer 1

Kelvin cycle is known as C3 cycle as in the CO2 Fixation stage,the CO2 diffuses into the stroma of the chloroplast in mesophyll cells and added to the five-carbon acceptor ribulose-1,5-bisphosphate yielding a six-carbon intermediate product which is hydrated to produce two molecules of three-carbon 3-phosphoglycerate or phosphoglyceric acid (3-PGA) as the first stable product.

Rubisco (catalyst)
CO2 + RuBP ----------------------------------> 2 3-PGA

This first stable product (3-PGA), is a three-carbon compound thats why this mechanism of photosynthesis is called C3 Cycle.

Answer 2

Kelvin cycle is known as C3 cycle..as in the CO2 fixation stage..the CO2 diffuses into the stroma of the chloroplast in mesophyll cells and added to the five carbon acceptor ribulose-1,5-bisphosphate yielding a six-carbon intermediate product which is hydrated to produce two molecules of three-carbon 3-phosphoglycerate or phosphoglyceric acid (3-PGA)as the first stable product.

Rubisco(catalyst)

CO2 + RuBP -------------------------->2,3-PGA

This first stable product (3-PGA),is a three-carbon compound that's why this mechanism of photosynthesis is called C3 cycle
