Why do c4 plants avoid Photorespiration?

Why do c4 plants avoid Photorespiration? C4 plants largely bypass photorespiration by using an extension of the Calvin-Benson cycle to pump only CO2, and not oxygen, into the bundle sheath cells where the RUBISCO reaction occurs. C4 plants can maintain a high, local concentration of CO2 for RUBISCO activity without raising cellular oxygen levels. Why … Continue reading Why do c4 plants avoid Photorespiration?
