Compare and contrast CAM and C4 photosynthetic pathways. Discuss evolutionary factors that led to the emergence of PEPcarboxylase.

Homework Answers

Answer #1
Characteristics C4 photosynthesis CAM photosynthesis
1. Kranz Anatomy Presesnt Absent
2.CO2:ATP:NADPH ratio 1:5:2 1:6.5:2
3.Carboxylating Enzyme

In Mesophyll-PEP carboxylase

In bundle sheath-RuBP Carboxylase

In dark--PEP carboxylase

In light-RuBP carboxylase

4. Initial CO2 acceptor PEP PEP
5.First stable product oxaloacetate oxaloacetate
6. optimum temperature for photosynthesis 30-40 degree celcius >40 degree cecius
7. CO2 compensation point(ppm) 0-10 0-5 in dark
8.Photorespiration Not easly detectable Detectatble in afterno9.on
9.Calvin cycle operative Along with Hatch and Slack cycle long with Hatch and Slack cycle

PEP Carboxylase is present in both C4 and CAM plant. it can fix the carbon at very low concentrataion of hydrogen carbonate in comparision RuBisCo. Due to PEP carboxylase plant can suvive in extreme environmet like heat and lack of water.
