C3 and C4 pathways
C3 and C4 pathways
| C3 Pathway | C4 Pathway | ||
| i. | In the C3 pathway, the first product of carbon fixation is a 3 carbon atom compound 3-phosphoglyceric acid. | i. | In the C4 pathway, the first product of carbon fixation is oxaloacetic acid, a 4 carbon atom compound. |
| ii. | Photorespiration occurs in C3 plants. | ii. | Photorespiration rarely occurs. |
| iii. | Plants are adapted to all climates except saline conditions. | iii. | Plants are adapted to tropical climate and can tolerate halophytic conditions. |
| iv. | This pathway is less expensive and requires only 18 molecules of ATP for the synthesis of one molecule of glucose. | iv. | This pathway is more energy expensive and requires 30 molecules of ATP for the synthesis of one molecule of glucose. |
