WebAug 10, 2024 · In C4 plants, the photosynthetic apparatus is partitioned between two cell types: mesophyll cells and bundle sheath. The enzymes involved in the C4 carbon cycle and assimilation of nitrogen are localized in a cell-specific manner. WebOct 4, 1996 · C4 plants largely bypass photorespiration by using an extension of the Calvin-Benson cycle to pump only CO 2, and not oxygen, into the bundle sheath cells where the RUBISCO reaction occurs. C4 plants can maintain a high, local concentration of CO 2 for RUBISCO activity without raising cellular oxygen levels. The Biology Project
