The first stable product of photosynthesis is – |
| A. | Starch |
| B. | Sucrose |
| C. | Phosphoglyceric acid |
| D. | Glucose |
| Answer» C. Phosphoglyceric acid | |
|
Explanation: The first product of photosynthesis is a three-carbon compound called phosphoglyceric acid and phosphoglyceraldehyde. Almost immediately, two of these join to form a glucose molecule. Certain herbaceous plants such as sugarcane, corn, and sorghum, form as the first products of photosynthesis not three-carbon but four-carbon compounds— oxalacetic, malic, and aspartic acids. |
