First pathway of photosynthesis
WebThere are two important adaptations that allow C4 plants to do this: First, C4 plants use an alternate enzyme for the first step of carbon fixation. This enzyme is called phosphoenolpyruvate (PEP) carboxylase, and it has no oxygenase activity and has a much higher affinity for CO2 than rubisco. As the name “PEP carboxylase” suggests, the ...

WebThe Calvin cycle reactions can be divided into three main stages: carbon fixation, reduction, and regeneration of the starting molecule. Here is a general diagram of the cycle: \text {CO}_2 CO2 Regeneration. [See a diagram that shows the molecular structures] Carbon fixation. A \text {CO}_2 CO2 WebThe first step in the NADP-ME type C 4 pathway is the conversion of pyruvate (Pyr) to phosphoenolpyruvate (PEP), by the enzyme Pyruvate phosphate dikinase (PPDK). This reaction requires inorganic phosphate and ATP plus pyruvate, producing PEP, AMP, and inorganic pyrophosphate (PP i ).
