In photorespiration, there is no formation of ATP. Instead, ATP are utilised and there is loss of carbon of 5C sugars as carbon dioxide. ${\mathrm{C}}_4$ plants show Kranz anatomy in their leaves. Optimum temperature for ${\mathrm{C}}_3$ plants for photosynthesis is $20-{25}^{\mathrm{o}}\mathrm{C}$. ${\mathrm{C}}_3$ cycle was first discovered by Calvin and Basham, and hence it is also known as Calvin cycle.
