Sa+b​

Answer 1

Answer:

RuBisCo is an enzyme that acts both as a carboxylase and oxygenase. ... It carries out more carboxylation in the C4 plants as these plants have special mechanism that increases the concentration of the CO2 at the enzyme site. There is no photorespiration in the C4 plants and thus oxygen does not bind to the RuBisCo enzyme.

Answer 2

Explanation:

• Because those plants perform special process or mechanism that literally increases the concentration of co2 at the site of these enzymes....
• oxygen does not bind on RuBisCO as these plants lack photo respiration
