Factors affecting photosynthesis
-
With reference to factors affecting the rate of photosynthesis, which of the following statements is not correct?
$C_4$ plants, not $C_3$, have the higher temperature optimum.
In $C_3$ plants, photosynthesis decreases at higher temperatures due to increased photorespiration. $C_4$ plants have a higher temperature optimum, partly because pyruvate phosphate dikinase is sensitive to low temperature.
$C_4$ pathway (Hatch–Slack pathway)
-
Phosphoenol pyruvate (PEP) is the primary $CO_2$ acceptor in:
PEP carboxylase fixes $CO_2$ in $C_4$ mesophyll.
PEP is a 3C compound which serves as the primary $CO_2$ acceptor in the mesophyll cell cytoplasm of $C_4$ plants like maize, sugarcane and $Sorghum$.
