Question

C4 plants are more efficient and grow faster than do c3 plants why is this the case

Answer 1

In C4 plants photorespiration does not occur. This is because they have a mechanism that increases the concentration of CO2 at the enzyme site. ... The C4 pathway is certainly more efficient than the C3 pathway in the sense of carbon fixation. The enzyme responsible for this step is RuBisCO

Answer 2

because C4 plants do not undergo a wasteful process named oxidative decarboxylation in which no ATP or energy is released rather it consumes CO2 .... Therefore due to absence of this process C4 plants more efficient than C3 plants..☺️☺️
