The C4 -plants differ from the C3 -plants with reference to the
A. Compound that accept CO2 in carbon assimilation
B. Type of the first stable product produced
C. Number of ATP's required to from starch
D. All of the above
Answer: Option D
Solution(By Examveda Team)
The C4 -plants differ from the C3 -plants concerning the Compound that accept CO2 in carbon assimilation, the Type of the first stable product produced, and also the Number of ATP's required from starch.C3 photosynthesis produces a three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle.
The first stable compound produced in the Calvin cycle is a 3-carbon compound, which is 3 phosphoglyceric acid (PGA). In the C4 plant, the first stable product is a 4-carbon compound, which is Oxaloacetic Acid (OAA).
In the C4 cycle of photosynthesis, a total of 30 ATPs are needed whereas, For the C3 cycle to repair 6CO2, 18 ATPs are needed.
