Solution
C3 photosynthesis is limited during hot, dry weather.
Here's why:
- C3 photosynthesis: This is the most common type of photosynthesis where the first product of carbon fixation is a three-carbon compound, 3-phosphoglycerate. In hot and dry conditions, the stomata (pores in the leaf) close to prevent water loss. This also prevents CO2 from entering the leaf and O2 from leaving. As a result, the concentration of O2 increases relative to CO2 inside the leaf. This causes an enzyme involved in C3 photosynthesis,
