Answer 2

➬Photorespiration refers to a process in plant metabolism where the enzyme RuBisCO oxygenates RuBP, wasting some of the energy produced by photosynthesis.

➬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.
