http://hyperphysics.phy-astr.gsu.edu/hbase/Biology/phoc.html WebThe C4 acid, oxaloacetic acid (OAA), degrades via the Hatch and Slack Pathway, releasing CO2. This guarantees a high intercellular CO2 concentration. As a result, in C4 plants, RuBisCO acts as a carboxylase enzyme rather than an oxygenase. This is why C4 plants are more productive.

WebJun 18, 2013 · Generally, photosynthesis and C assimilation occur in chloroplasts of leaf mesophyll cells and additionally in bundle sheath cells in C4 plants. The C fixed during photosynthesis is converted into sugar or sugar derivatives in photosynthetic source cells then is distributed to distal sink cells. WebThe carbon-fixation pathway begins in the mesophyll cells, where carbon dioxide is converted into bicarbonate, which is then added to the three-carbon acid … WebSep 14, 2024 · In C4 plants, PEPC, OMT, NADP-MDH, PPDK, and carbonic anhydrase (CA) are expressed specifically in mesophyll cells, whereas RuBisCO, DIT1, and NADP-ME are expressed preferentially in the BS ( Weber and von Caemmerer, 2010; Gowik et al., 2011 ).
