Does respiration always involve the release of CO2 as a waste?

Description : Does respiration always involve the release of CO2 as a waste?

Last Answer : I believe that what it means is that for each molecule of CO2 that the plant takes in, it breaks the C and O2 bond to use the carbon in its food-production process. The leftover O2 molecule ... the lungs. I expect that something similar occurs with plants, except for the lungs thing, obviously.)

Why does not photorespiration take place in C4 plants? -Biology

Description : Why does not photorespiration take place in C4 plants? -Biology

Last Answer : Photorespiration occurs due to the oxygenase activity of RuBisCO. When the concentration of O2 is high, RuBisCO binds to oxygen and carries out photorespiration. C4 plants have a mechanism of maintaining high CO2 concentration at the enzyme site, thus photorespiration does not occur
