Summary Introduction

To determine:

The reason behind naming the Calvin cycle as the ${\text{C}}_{\text{3}}$ pathway.

Introduction:

The two stages of photosynthesis are the light reactions and the carbon reactions. The carbon reaction or the Calvin cycle occurs in the “stroma” of chloroplasts. In the Calvin cycle, adenosine triphosphate ($\text{ATP}$) and nicotinamide adenine dinucleotide phosphate $\text{(NADPH})$ assemble ${\text{CO}}_{\text{2}}$ molecules into three-carbon carbohydrate molecule. The three- carbon carbohydrate eventually forms “glucose” and other sugars.
