Select all of the following in which carbon fixation is limited during hot, dry weather.Group of answer choicesCAM photosynthesisC3 photosynthesisC4 photosynthesis
Solution
C3 photosynthesis is limited during hot, dry weather.
Here's why:
-
C3 photosynthesis is the most common form of photosynthesis in plants. It is named for the 3-carbon compound produced in the first step of the process.
-
During hot, dry weather, plants close their stomata (pores) to reduce water loss. However, this also prevents CO2 from entering the plant, which is necessary for photosynthesis.
-
Without sufficient CO2, the enzyme that catalyzes the first step of C3 photosynthesis (RuBis
